Terms of service

Last updated: 9 August 2026

IMPORTANT: These Terms govern the use of the JewelTec platform operated by JEX Holdings Ltd. By creating an account, accessing, or using the Platform, you agree to be legally bound by these Terms. If you do not agree, you must not access or use the Platform.

1. These Terms are a legally binding agreement between (a) you (the business user of the Platform) and (b) JEX Holdings Ltd (company number 16479946\) whose registered office is at 8-9 Greville Street Greville Street, London, England, EC1N 8SB ("JewelTec", "we", "us" or "our").

2. The "Platform" means the JewelTec websites, mobile applications, application programming interfaces (APIs), messaging and trading tools, digital storefront tools, pricing and analytics tools, and any other services we make available from time to time.

3. You can contact us at: [email protected].

4. These Terms incorporate (and are to be read together with) any documents we expressly incorporate by reference, including our Privacy Policy, Cookie Policy, Fee Schedule, Listing Rules/Prohibited Goods Policy, and any feature-specific terms that we present to you within the Platform.

5. If there is any conflict between these Terms and any incorporated document, the following order of precedence applies (highest first): (a) feature-specific terms presented at the point of use; (b) the Fee Schedule; (c) the Trading Rules and Buyer Protection Rules (Schedule 1); (d) the Listing Rules/Prohibited Goods Policy (Schedule 2); (e) these Terms; and then (f) any other incorporated documents.

1. The Platform is exclusively for professional users in the jewellery, watch, diamond, gemstone and precious metals industries (and any related professional services we permit). You must not use the Platform as a consumer.

2. By using the Platform you warrant that you are acting for purposes wholly or mainly relating to your trade, business, craft or profession. If you are an individual you also warrant you are not acting for personal use.

3. You acknowledge that consumer protection legislation such as the Consumer Rights Act 2015 and the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 does not apply to your use of the Platform or any business-to-business transactions you enter into via the Platform.

4. If you use any feature to sell to end-consumers (for example, the Digital Storefront tools), you are solely responsible for complying with all consumer law and e-commerce requirements that apply to your own consumer sales (see clause 14).

1. In these Terms, capitalised words have the meanings given in Schedule 3 (Definitions).

2. Headings are for convenience only and do not affect interpretation. Words in the singular include the plural and vice versa. References to a person include a company and vice versa.

1. You must create an Account to use the Platform. You must provide complete and accurate information and keep it up to date. You must ensure that all individuals using your Account (including your employees, contractors and agents) are authorised and comply with these Terms.

2. If you are using the Platform on behalf of a business, you represent and warrant that you have the authority to bind that business to these Terms.

3. Access is conditional upon successful completion of our identity, business and compliance checks (KYC/KYB) and any ongoing monitoring. We may require documents such as Companies House records, VAT registration, proof of trading premises, trade references, an anti-money laundering (AML) policy, and/or a letter of good standing from a recognised trade body (e.g., RJC or NAG).

4. We may use third-party service providers to carry out verification, sanctions screening, PEP screening, transaction monitoring, fraud checks and similar checks. You authorise us to share your information with such providers and to receive results and risk indicators from them.

5. You must notify us within 48 hours of any material change, including changes to beneficial ownership, directors/partners, trading name, address, VAT status, bank details, insurance, regulatory status, or if you become (or reasonably suspect you may become) subject to criminal investigation, insolvency proceedings, enforcement action, or financial or trade sanctions.

6. We may require additional information at any time on a risk-based basis (including source of funds/source of wealth information) and may refuse, suspend or restrict your access if you do not provide it promptly.

7. We may accept or reject any application for an Account in our absolute discretion and are not obliged to give reasons. We may impose limits by category, jurisdiction, transaction size, volume or other risk factors.

1. The Platform may assign or display account reputation signals, including a "Trust Score", trading history, delivery performance, dispute rate and other indicators. These are generated using automated tools and/or human review and are provided for information only; they are not guarantees of performance, solvency or integrity.

2. We may monitor usage and transactions for fraud prevention, compliance, platform integrity and security. We may also take actions described in clause 16 (Suspension and termination) if we identify risk indicators or breaches.

3. Trigger events may include (without limitation): repeated late deliveries, repeated failed hallmark or authenticity checks, unusually high dispute/chargeback rates, suspected counterfeit or stolen goods, suspected sanctions/AML issues, abusive behaviour, fee circumvention, or any other event that in our reasonable opinion creates material risk to the Platform or other users.

1. We provide a technology platform and rule framework to help verified businesses discover each other, communicate, list goods and services, and (where enabled) facilitate payment processing via third-party payment partners.

2. Unless we expressly agree in writing otherwise, JewelTec is not a party to any contract for the sale or purchase of goods or services between users. Any contract is directly between the buyer and the seller (or the professional service provider) and users are solely responsible for their own dealings.

3. We do not act as an agent, auctioneer, broker, dealer, merchant of record, insurer, shipper or custodian. We do not take possession of goods. We do not provide legal, tax, financial, investment or valuation advice.

1. Subject to these Terms and payment of all Fees due, we grant you a limited, non-exclusive, non-transferable, revocable licence to access and use the Platform for your internal business purposes during the Term.

2. You must not (and must ensure your Authorised Users do not): (a) misuse the Platform; (b) attempt to gain unauthorised access; (c) introduce malware; (d) scrape, harvest or extract data; (e) circumvent or attempt to circumvent Platform fees, controls or policies; (f) interfere with the integrity or performance of the Platform; (g) use the Platform to infringe any rights or break any law; or (h) use the Platform to build or support a competing service.

3. You must maintain strong credentials, keep login details confidential and implement appropriate account security. You are responsible for all activity carried out using your Account, whether authorised or not.

1. You are responsible for all information you upload or make available on the Platform ("User Content"), including listings, descriptions, certificates, photographs, videos, messages, reviews and reports.

2. You warrant that: (a) you have all rights to upload the User Content; (b) it is accurate, not misleading and kept up to date; (c) it does not infringe third-party rights; and (d) it complies with these Terms, our Listing Rules and all Applicable Law.

3. We may remove, disable access to, or refuse to publish any User Content at any time, without liability, including where we suspect it is unlawful, misleading, defamatory, counterfeit, stolen, infringes rights, or breaches our policies.

4. You must not list or trade Prohibited Goods (see Schedule 2). This includes counterfeit items, stolen items, items derived from or linked to criminal property, conflict goods (including rough diamonds without Kimberley Process compliance), and any goods whose sale or export/import is restricted or illegal.

5. Communication standards. You must behave professionally, honestly and lawfully. Harassment, threats, discrimination, abuse, doxxing, and deceptive conduct are prohibited.

1. When users transact via the Platform, the buyer and seller enter into a direct contract with each other. Unless the parties agree otherwise in writing within the Platform, the default trading rules in Schedule 1 apply and are incorporated into that contract.

2. We may provide tools to create digital records, orders, invoices, delivery confirmation, acceptance and dispute workflows. These are designed to create an audit trail and standardise evidence. They do not make us a party to the transaction.

3. You are responsible for complying with all Applicable Law relating to goods you list or sell, including (as applicable) hallmarking requirements, trade descriptions, disclosure of treatments, intellectual property, import/export, customs declarations, anti-money laundering, sanctions and tax/VAT.

1. Payment processing is provided by one or more third-party payment service providers (each a "Payment Partner"). Currently, our primary Payment Partner is Stripe. By using payment features you agree to the Payment Partner’s terms (including the Stripe Connected Account Agreement) and you authorise us to share information with the Payment Partner.

2. JewelTec does not provide payment services and does not hold client money at any point. Any funds you pay are received and held (if applicable) by the relevant Payment Partner in accordance with that Payment Partner’s own terms and applicable regulation. Depending on the value and nature of a Transaction, the Payment Partner used may differ — see Schedule 1, Section G (High-Value Transactions) for Transactions of £25,000 or more. Any "escrow" or delayed payout functionality is implemented through the relevant Payment Partner’s own services and is not a regulated escrow service provided by JewelTec. Where a Transaction is routed to a regulated escrow provider under Section G, that service is provided by the relevant Payment Partner.

3. We may instruct the Payment Partner to pay out, refund, reverse or hold amounts in accordance with these Terms, the Trading Rules and our dispute and risk policies. You authorise us to give such instructions.

4. You must pay all subscription fees, transaction fees and processing fees described in the Fee Schedule. Fees are non-refundable except where required by law or expressly stated otherwise. We may change Fees with at least 30 days’ notice (or sooner where required by the Payment Partner or to respond to legal/regulatory change).

5. You authorise us to set off and/or instruct the Payment Partner to deduct any amounts you owe to us (including Fees, negative balances, chargebacks, administration charges and indemnities) from amounts otherwise payable to you via the Platform.

6. If any amount payable to us (including subscription fees processed by card through Stripe Billing) is reversed, disputed, charged back or otherwise unpaid, and your Account shows a negative balance, you authorise us and/or the Payment Partner to: (a) recover the negative balance from you; (b) debit your saved payment method(s); (c) offset against future payouts; and (d) impose a reasonable administration fee per instance (currently £250) reflecting internal and Payment Partner costs. For the avoidance of doubt, Transactions between users conducted via Open Banking payment do not carry card-scheme chargeback risk; payment disputes, reversals and unauthorised payment claims arising from such Transactions are instead governed by Schedule 1, Sections F and G.

7. We (and/or the Payment Partner) may place holds, reserves or delayed payouts on your Account or specific transactions to manage chargeback, fraud, compliance or operational risk. If your Account is terminated for cause, we may instruct the Payment Partner to hold funds for up to 180 days (or longer if required by the Payment Partner or Applicable Law) to cover chargebacks, refunds, fines or other liabilities.

8. Where a transaction involves currency conversion, exchange rates are determined by the Payment Partner and/or our FX providers at the time(s) they process the conversion. If a refund is issued, the buyer will be refunded the amount in the original currency paid (to the extent possible), and the seller bears any FX difference unless we state otherwise in the Buyer Protection Rules.

9. Where the value of a Transaction is £25,000 or more, additional payment routing rules apply, including mandatory use of a regulated escrow provider — see Schedule 1, Section G (High-Value Transactions).

1. Users must attempt to resolve disputes directly with each other in good faith. We may provide a structured dispute process and may (but are not obliged to) facilitate communication, evidence collection and settlement discussions.

2. If a dispute relates to a transaction processed via a Payment Partner through the Platform, you authorise us to apply the dispute workflow in Schedule 1 (including placing holds and issuing refund/payout instructions) to protect the Platform and other users.

3. Before either party commences court proceedings against the other in relation to a Platform Transaction, the parties agree to engage in a 14-day good-faith discussion period. This clause does not prevent either party seeking urgent injunctive relief.

4. For disputes concerning technical characteristics (including diamond grading, treatments, metal fineness/purity, hallmarking, authenticity reports, or similar), we may require the parties to obtain an independent report from an appropriate recognised laboratory or expert (for example, GIA for diamonds/gemstones and/or an assay office for metal purity). The expert’s determination will be final and binding for the limited purpose of our instructions to the Payment Partner on whether to release funds or process a refund under the Buyer Protection Rules. It does not prevent either party pursuing claims against the other outside the Platform.

5. Unless we state otherwise: (a) the party raising the technical allegation must pay the upfront cost of the report; (b) if the allegation is fully or partially upheld, the other party must reimburse that cost; and (c) if the allegation is not upheld, the alleging party bears the cost.

6. Any facilitation, recommendations or determinations we make are made for Platform administration purposes only. We do not provide legal advice and we are not liable for outcomes of disputes between users.

1. Users are responsible for agreeing shipping terms for each Transaction (including Incoterms, packaging, declared value, and import/export documents). Unless agreed otherwise in the Transaction record, shipping is DAP (delivered at place) to the buyer’s nominated delivery address and the seller remains responsible for safe delivery and for insuring the goods until successful delivery to the buyer.

2. We may specify approved or "Mandatory" carriers for certain categories, values, jurisdictions or dispute-protected transactions. If a seller uses a non-approved carrier or fails to follow required shipping instructions (including declared value and insurance requirements), that Transaction may be ineligible for Buyer Protection and/or the seller may bear the loss if the parcel is lost, delayed or damaged.

3. We are not a carrier and do not provide insurance. Any shipping labels or insurance offered through the Platform are provided by third parties and subject to their terms.

1. The Platform may allow users to advertise or discover professional services (for example, CAD design, diamond setting, engraving, repairs and similar services). Contracts for such services are directly between the customer and the service provider.

2. We may carry out limited checks or verification steps, but we do not guarantee any professional’s qualifications, competence, insurance (including public liability or professional indemnity), licensing, availability or performance. You must carry out your own due diligence.

3. We may charge a commission or referral fee for professional-service leads as described in the Fee Schedule.

1. The Platform may provide tools that allow you to create and operate your own online storefront (including consumer-facing storefronts) and to integrate inventory, pricing, checkout and payment processing.

2. You are the seller/merchant of record for any sales you make using these tools. End-customers are not our users for the purposes of these Terms (unless they separately create an Account). We are not a party to your contracts with end-customers.

3. You must ensure your storefront and sales practices comply with all Applicable Law, including consumer law (Consumer Rights Act 2015, Consumer Contracts Regulations 2013), e-commerce disclosure requirements, product safety, hallmarking, advertising standards, VAT and tax rules, and data protection. You must provide your own consumer terms, privacy information, returns policy and required disclosures.

4. If your consumer sales or storefront create legal, regulatory or reputational risk to JewelTec, we may restrict or disable the storefront feature for your Account.

1. The Platform may provide price indices, pricing tools, market analytics, inventory valuations and alerts. These are provided for general information only and are not advice. You remain responsible for your own pricing and trading decisions.

2. We make reasonable efforts to keep tools up to date, but we do not guarantee accuracy, completeness or timeliness. Prices may be volatile and third-party data may be delayed or inaccurate.

3. Any valuations we present are estimates for convenience only and do not constitute a formal appraisal or valuation for insurance, lending or accounting purposes.

1. You may close your Account at any time by giving at least 30 days’ notice, provided there are no open disputes, payment reversals, negative balances or pending Transactions. We may retain certain data for legal, compliance and audit purposes.

2. We may suspend, restrict or terminate your Account (including freezing access to features, listings, messaging or payment processing) immediately, without liability, where: (a) we suspect fraud, counterfeit/stolen goods, AML/sanctions risk, unlawful conduct, or material breach; (b) required by a Payment Partner or Applicable Law; (c) your Trust Score falls below required thresholds; or (d) you repeatedly breach policies or create unacceptable risk.

3. Upon termination, your licence to use the Platform ends. Clauses intended to survive termination (including payment obligations, indemnities, confidentiality, IP, limitation of liability, dispute resolution and governing law) will survive.

1. We (and/or our licensors) own all intellectual property rights in the Platform, including software, databases, the Real-Time Pricing Index, aggregated metadata, designs, trademarks and content we provide.

2. You grant us a worldwide, royalty-free, sublicensable licence to host, store, reproduce, display and otherwise use your User Content to operate, improve and promote the Platform, to create audit trails and to comply with Applicable Law. You also grant us the right to generate and exploit aggregated and anonymised insights derived from Platform activity, provided they do not identify you or your customers unless you have consented.

3. Except as expressly permitted in writing, you must not: (a) scrape, crawl, harvest or extract any data; (b) copy, reproduce, redistribute, sell or exploit Platform Data; (c) use Platform Data to create or improve any competing product or service; or (d) use Platform Data (including listings, price lists, indices, metadata or historical transaction information) to train, fine-tune, validate, benchmark, or otherwise develop any artificial intelligence or machine learning model.

4. Breach of clause 17.3 may cause irreparable harm. We may seek injunctive relief and you will be liable for all losses, costs and expenses (including legal costs on a full indemnity basis) arising from the breach. We may also charge you (as a debt) our reasonable investigation and enforcement costs, and we may terminate your Account immediately.

1. You must not use the Platform to identify or contact another user and then transact outside the Platform to avoid Fees or controls ("Circumvention").

2. If we reasonably determine Circumvention has occurred in connection with a Transaction opportunity introduced through the Platform, we may: (a) suspend or terminate Accounts; (b) invoice the parties jointly and severally for the Fees that would have been payable on the off-Platform transaction (calculated by reference to the value evidenced by messages, invoices, shipping documents or other evidence); and (c) charge an administration and investigation fee of up to £1,500 per incident (as a reasonable estimate of our costs).

3. Nothing in this clause limits our right to seek damages, injunctive relief or other remedies. This clause is intended to protect our legitimate interests in maintaining Platform integrity and funding the services we provide.

1. You must treat as confidential any non-public information you obtain through the Platform relating to another user’s business, pricing, inventory, contacts, transaction history or other commercial information ("Confidential Information").

2. You may use Confidential Information only for the purpose of evaluating and completing Transactions through the Platform. You must not disclose it to any third party except to your professional advisers or insurers on a need-to-know basis (who must be bound by confidentiality).

3. This clause does not apply to information that is public other than through breach, independently developed, or required to be disclosed by law/regulator/court (provided you notify the other party where lawful to do so).

1. We will process personal data in accordance with applicable data protection law (including the UK GDPR and Data Protection Act 2018\) and our Privacy Policy.

2. Where you receive personal data about another user (for example, contact details, delivery address or identity documents), you act as an independent controller and must process that data lawfully and securely and only for the purpose of the Transaction and compliance obligations.

3. We may share data with verification, payment, logistics, insurance and compliance partners and with regulators/law enforcement where required or appropriate to protect the Platform or comply with law. You acknowledge that in some circumstances we may be legally prohibited from informing you (including where doing so would constitute unlawful tipping-off).

1. The Platform is provided on an "as is" and "as available" basis. To the fullest extent permitted by law, we exclude all implied warranties, conditions and representations.

2. We do not guarantee that the Platform will be uninterrupted, secure or error-free, or that defects will be corrected. We may suspend access for maintenance, upgrades, security or operational reasons.

3. We do not guarantee that any user will complete a Transaction, pay, deliver, or that any goods are authentic, legal or as described. You are responsible for your own due diligence.

4. The Platform may integrate third-party services (including Stripe, carriers, insurers, data providers and labs). We are not responsible for third-party services and your use of them is subject to their terms.

1. Nothing in these Terms limits or excludes liability for: (a) death or personal injury caused by negligence; (b) fraud or fraudulent misrepresentation; or (c) any liability that cannot legally be limited or excluded.

2. Subject to clause 22.1, we will not be liable for any indirect or consequential loss, loss of profit, loss of revenue, loss of business, loss of goodwill/reputation, loss of anticipated savings, or loss of data.

3. Subject to clause 22.1, our total aggregate liability to you arising out of or in connection with these Terms (whether in contract, tort (including negligence), breach of statutory duty or otherwise) will not exceed the total Fees paid by you to JewelTec in the 12 months immediately preceding the event giving rise to the claim, or £1,000, whichever is greater.

4. You acknowledge that JewelTec is not responsible for losses arising from Transactions between users, including counterfeit goods, non-delivery, misdescription, payment reversals or disputes (whether arising via Open Banking payment, an Escrow Provider, or otherwise), customs seizures, taxes, or regulatory enforcement against you.

1. You will indemnify, defend and hold harmless JewelTec, its group companies, officers, directors, employees and agents from and against all claims, losses, liabilities, damages, costs and expenses (including legal costs on a full indemnity basis) arising out of or in connection with:

•your breach of these Terms, the Trading Rules or any policy;

•your breach of Applicable Law (including AML, sanctions, hallmarking and tax/VAT laws);

•any allegation that goods you listed, sold or supplied are counterfeit, stolen, unlawfully sourced, infringing, or otherwise illegal (including claims by rights holders, regulators or law enforcement);

•your User Content (including defamation, misleading statements or IP infringement);

•your mis-declaration of VAT, tax status, customs value, origin or other trade documentation; and

•any dispute between you and another user or third party.

1. These Terms and the incorporated documents form the entire agreement between you and us regarding the Platform and supersede all prior discussions, marketing materials and representations.

2. We may amend these Terms from time to time. We will notify you of material changes via the Platform or email. Continued use of the Platform after the effective date constitutes acceptance.

3. We may assign or transfer our rights and obligations under these Terms. You may not assign without our prior written consent.

4. If any provision is held invalid or unenforceable, it will be modified to the minimum extent necessary to make it enforceable, and the remainder will remain in effect.

5. Failure to enforce a provision is not a waiver.

6. Except for our group companies and service providers where expressly stated, no third party has rights under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of these Terms.

7. We are not liable for delay or failure to perform resulting from events beyond our reasonable control, including cyber-attacks, outages, supplier failures, pandemics, or governmental actions.

1. These Terms and any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with them are governed by the laws of England and Wales.

2. The courts of England and Wales have exclusive jurisdiction to settle any dispute or claim arising out of or in connection with these Terms or the Platform (without prejudice to our right to seek injunctive relief in any jurisdiction).

A. Scope

1. These Trading Rules apply to each Transaction between users that is agreed, booked, ordered or otherwise concluded via the Platform, unless the parties expressly agree different terms in writing within the Platform.

2. Where payment processing through a Payment Partner is used, these Trading Rules also govern JewelTec’s administration of the Payment Partner workflow (including delayed payout, holds and refunds) as a set of Buyer Protection Rules.

B. Contract formation and documents

3. Listings are invitations to treat. A buyer places an order or sends an offer through the Platform. A contract forms when the seller expressly accepts within the Platform (or when the Platform indicates acceptance, for example via an automated “Buy Now” confirmation).

4. The Platform record (including listing, messages, agreed price, currency, delivery terms, certificates and acceptance/dispute events) constitutes the primary evidence of the contract. Users should not rely on off-platform communications.

C. Seller obligations and warranties

5. The seller warrants that, at the time of dispatch and at the time of delivery, the goods:

•match the description, photographs, certificates and disclosures made on the Platform;

•are authentic (where branded), genuine and not counterfeit;

•are free from liens and encumbrances and the seller has good title and the right to sell;

•are not stolen, unlawfully sourced, or derived from criminal property;

•comply with Applicable Law, including hallmarking requirements, advertising and trade description laws, sanctions and AML laws, and import/export restrictions; and

•do not infringe any third-party intellectual property rights.

6. Hallmarking (UK). Where goods are supplied into the UK and are subject to hallmarking requirements, the seller must ensure appropriate hallmarking and/or exemption applies. A failed hallmark or fineness test is a material breach.

7. Diamond and gemstone treatments. The seller must disclose all treatments and enhancements (including, without limitation, laser drilling, fracture filling, HPHT, irradiation, coating, diffusion, clarity enhancement, dyeing and any similar treatments) and must provide supporting certification where reasonably available. Non-disclosure is a material breach.

8. Rough diamonds. The seller must comply with the Kimberley Process and any import/export rules. Where required, the seller must upload a digital copy of the relevant Kimberley Process Certificate and retain records for at least 5 years.

D. Shipping, risk and title

9. Unless otherwise agreed in the Transaction record, the seller must dispatch within 2 Business Days of acceptance and use an approved carrier where required.

10. Risk of loss passes to the buyer on delivery to the buyer’s nominated address (as shown by tracked delivery). Title transfers only when (a) the buyer has paid in full and (b) the Inspection Period has expired without dispute or the buyer has accepted the goods.

11. If the buyer arranges collection or nominates a carrier outside any Mandatory Carrier requirement, risk passes on collection by that carrier, provided the seller has complied with agreed packaging and handover requirements.

E. Inspection period, acceptance and returns

12. Where Buyer Protection is used, the buyer has 72 hours from the buyer’s confirmed receipt of the goods (recorded by the buyer marking the goods received in the Platform) to inspect the goods and either accept them or raise a dispute through the Platform, provided that if the buyer does not confirm receipt, the Inspection Period will in any event begin, and the buyer will be treated as having received the goods, no later than 96 hours after the carrier’s tracked delivery confirmation (the “Inspection Period”).

13. Acceptance occurs when: (a) the buyer clicks “accept” in the Platform; or (b) the Inspection Period expires without a dispute; or (c) the buyer alters the goods or removes/compromises tamper-evident seals (for example resizing rings, removing links, removing “void” stickers, opening a watch case, or any other alteration beyond reasonable external inspection).

14. If the buyer raises a dispute within the Inspection Period, the buyer must: (a) provide evidence (photos/video) promptly; (b) keep the goods safe and insured; and (c) comply with any return instructions. Failure may result in release of funds to the seller.

15. Returns must be made using the required shipping method and insurance. Goods must be returned in the same condition as delivered, with all original components, certificates and packaging. If the seller alleges tampering, we may require expert review.

16. Watch inspections. If the buyer (or their agent) opens a watch case or removes a movement, they do so at their own risk and acknowledge it may void manufacturer warranties and may affect value. Unless the parties agreed otherwise in advance, such opening constitutes acceptance for Buyer Protection purposes unless required by an agreed independent authenticator.

F. Payment release, refunds and disputes

17. On acceptance, we will instruct the Payment Partner to release funds to the seller (less Fees).

18. If a dispute is upheld, we may instruct a refund to the buyer and may reverse or withhold payout to the seller. If only part of the goods are disputed, we may apply partial refund logic if supported by evidence and agreed by both parties.

19. Technical disputes. Where expert determination is required, the goods may need to be sent to an agreed lab/expert. The parties must cooperate and provide documentation. The expert’s written determination will be final for release/refund instructions.

20. JewelTec’s role. All determinations under these Rules are administrative decisions for Platform payment workflow purposes only and do not constitute legal determinations of liability between buyer and seller.

G. High-Value Transactions (£25,000 and above)

21. Where the value of a Transaction is £25,000 or more, payment must be made via a regulated escrow provider engaged by JewelTec for this purpose (each an “Escrow Provider”) rather than via Open Banking payment. As at the date of these Terms, JewelTec’s Escrow Providers are Transpact (for GBP/UK domestic Transactions) and Escrow.com (for international, multi-currency or card-based Transactions), or such other regulated provider as we may notify from time to time.

22. Where an Escrow Provider is used: (a) the buyer pays the Escrow Provider directly, and funds are held by the Escrow Provider, not JewelTec, pending release; (b) JewelTec is not a party to the escrow arrangement and does not at any point hold, control or have access to the funds; (c) release of funds to the seller is governed by the Escrow Provider’s own terms and procedures, which will reflect the Inspection Period, acceptance and dispute principles in this Schedule 1 so far as the Escrow Provider’s process permits; and (d) any payment dispute, reversal or chargeback arising from a Transaction routed to an Escrow Provider is resolved under that Escrow Provider’s own terms, and JewelTec’s role is limited to providing authentication findings and evidence to assist that process.

23. Users may also elect to use an Escrow Provider on a voluntary basis for Transactions below £25,000, subject to the Escrow Provider’s own fees and requirements, by selecting this option before payment is made.

24. We will disclose to the buyer, before payment, which payment route applies to a Transaction and, where relevant, which Escrow Provider will be used and the buyer protections that apply as a result.

1. You must not list, sell, purchase, offer or facilitate any of the following via the Platform (each “Prohibited Goods”):

•counterfeit items, replicas, "superfakes" or any item infringing trade marks, designs or copyrights;

•stolen items, items linked to theft, burglary, robbery or any criminal property;

•rough diamonds or other restricted items without required certificates or legal documentation (including Kimberley Process compliance where applicable);

•goods subject to sanctions, embargoes or trade restrictions, or involving sanctioned persons;

•goods made from or containing restricted wildlife products (including ivory, certain corals, tortoiseshell) contrary to CITES or other wildlife trade rules;

•any item whose sale, export, import or possession is unlawful in the relevant jurisdictions; and

•any other categories we designate as prohibited or restricted in the Platform from time to time.

2. We may require additional disclosures, documents or certification for certain categories (for example, branded watches, high-value diamonds, bullion, or items shipped cross-border).

3. We may remove listings, suspend accounts and share information with rights holders, regulators or law enforcement where we suspect Prohibited Goods or unlawful conduct.
