User agreement for Tailor Diamonds customers and website users

User Agreement

EN — User Agreement

Effective Date: 03 July 2026 Operator: Tailor Diamonds Limited (Hong Kong) Applicable Regions: Worldwide cross-border e-commerce for lab-grown diamond jewellery, with primary markets in Hong Kong, Mainland China, the United States, the United Kingdom, the European Union, Canada, Australia, the Middle East, and Southeast Asia.

By accessing, browsing, registering an account, or placing an order on tailordiamonds.com (the “Website”) or any affiliated sub-domain, application, social-commerce channel, or customer-service interface operated by Tailor Diamonds Limited (“Tailor Diamonds”, “we”, “us”, “our”), you (“the customer”, “user”, “you”, “your”) confirm that you have carefully read, fully understood, and voluntarily agreed to be bound by every clause of these User Agreement (the “Agreement”). If you do not agree with any portion of this Agreement, you must immediately stop using the Website, close any saved shopping carts, and refrain from initiating or completing any purchase.

This Agreement is written in English and Chinese. In the event of any conflict, ambiguity, or interpretive discrepancy between the two language versions, the English version shall prevail for the purpose of cross-border legal compliance, customs declarations, and international dispute resolution, unless mandatory local consumer-protection law in your country of residence explicitly requires otherwise.

Section 1 — Agreement Validity, User Eligibility & Account Integrity

1.1. Age and Legal Capacity. You represent and warrant that you are at least 18 years of age (or the age of majority in your jurisdiction, whichever is higher) and possess full civil capacity to enter into binding contracts for high-value cross-border jewellery transactions. If you are placing an order on behalf of another person, an organisation, or a minor, you confirm that you have obtained proper authorisation and that the ultimate beneficiary also meets these eligibility criteria.

1.2. KYC and Anti-Money-Laundering. Because lab-grown diamonds are high-value movable goods capable of being used for value transfer, we reserve the right to perform Know-Your-Customer (KYC) verification at any stage, including before order confirmation, before shipment, or after delivery. Verification may require a government-issued photo ID, proof of address, proof of funds, source-of-wealth declaration, or a short identity-verification video call. Failure to complete verification within fourteen (14) calendar days of request may result in order suspension, refund to original payment method, and account termination.

1.3. Prohibited Activities. The following activities are strictly forbidden and may be reported to relevant authorities: using the Website for money laundering, terrorist financing, sanctions evasion, fraud, tax evasion, illicit cross-border capital flow, or any transaction involving funds derived from criminal activity. We cooperate fully with law-enforcement agencies, financial intelligence units, and customs administrations in multiple jurisdictions.

1.4. Compliance with Synthetic-Diamond Law. Lab-grown diamonds are not subject to the Kimberley Process Certification Scheme (which regulates rough natural diamonds and conflict diamonds). However, we strictly comply with all applicable laws governing the import, export, re-export, advertising, and origin-disclosure of synthetic gemstones, including but not limited to the U.S. Federal Trade Commission (FTC) Jewelry Guides, the EU REACH Regulation, California Proposition 65, the UK Modern Slavery Act disclosure requirements, and Mainland China’s GB standards for laboratory-grown diamond nomenclature.

1.5. Right to Update. We may amend, supplement, or restate this Agreement at any time to reflect changes in product mix, legal requirements, payment-processor rules, or carrier conditions. Updates take effect seven (7) calendar days after publication on the Website, with the “Effective Date” revised accordingly. Continued browsing or subsequent orders constitutes acceptance of the updated Agreement. We will use commercially reasonable efforts to notify registered users of material changes by email or on-site banner; however, it remains your responsibility to review this page periodically.

Section 2 — Product Definition, Disclosure & Compliance Labeling

2.1. Clear Material Identification. Every diamond sold by Tailor Diamonds is a laboratory-grown (lab-created, man-made, cultivated) diamond, produced by either the High-Pressure High-Temperature (HPHT) method or the Chemical Vapour Deposition (CVD) method. We never sell natural mined diamonds, moissanite, cubic zirconia, white sapphire, or any other diamond simulant under the term “diamond”. The product title, the invoice, the certificate, and the packaging all clearly state “Lab Grown Diamond” / “Laboratory-Grown Diamond” / “培育钻石”.

2.2. No Misrepresentation. We strictly distinguish lab-grown diamonds from natural diamonds, simulants, and treated stones. We do not misrepresent origin, growth process, post-growth treatment, colour enhancement, or clarity enhancement. If a stone has been subjected to any post-growth process such as HPHT annealing for colour improvement or irradiation, this is fully disclosed in the product page, certificate, and accompanying Lab-Grown Diamond Disclosure Statement.

2.3. Full 4C + Origin Disclosure. Each stone is graded on the internationally recognised 4C standard — Carat, Colour, Clarity, Cut — plus fluorescence, polish, symmetry, growth method (CVD/HPHT), and country of final grading. Every centre stone of 0.30 carat and above ships with an IGI (International Gemological Institute) or GIA (Gemological Institute of America) Lab-Grown Diamond Report, which is independently verifiable through the issuing laboratory’s online report-check service. Reports are unique to each stone by laser-inscribed serial number.

2.4. Normal Physical Characteristics. Subtle differences in colour appearance under different lighting, minor variations in fire and scintillation, faint metallic inclusions specific to the growth method, faint graining lines, and slight blue or yellow tint are inherent physical attributes of laboratory-grown diamonds. These are not considered manufacturing defects and are not grounds for return, refund, or exchange.

2.5. No Hidden Treatments. We do not sell diamonds that have undergone undisclosed coating, fracture filling, laser drilling for clarity enhancement, colour irradiation, or HPHT colour annealing without explicit disclosure. Every Tailor Diamonds stone is supplied in its as-grown and disclosed state.

2.6. Photography Disclaimer. Product photography is taken under controlled 5500K daylight-balanced lighting. Slight differences in screen calibration, ambient lighting, photography angle, and post-processing mean that the on-screen appearance may differ marginally from the actual stone. Such visual variance is normal and is not a basis for “not as described” claims.

Section 3 — Orders, Customisation, Production & Return Policy

3.1. Made-to-Order Production. A significant portion of our catalogue — including loose-stone selection, bespoke engagement rings, custom wedding bands, engraved pendants, personalised earrings, and any product marked “Made to Order” — is produced specifically for you based on your confirmed parameters (stone choice, metal, ring size, engraving text, setting style). Once production has commenced, deposits are non-refundable, orders cannot be cancelled, and the 7-day “no-reason” return right does not apply, because the item has no resale value to another customer in its customised form.

3.2. In-Stock Items (Pre-Shipment). For in-stock items that have not yet been dispatched, you may request changes to size, engraving text, or a swap for an equivalent in-stock variant of equal or greater value (price difference payable by you). We will do our best to accommodate, but cannot guarantee changes once the carrier label has been generated.

3.3. Post-Shipment Returns. After dispatch, returns are accepted only in the following circumstances: the stone’s measured parameters differ materially from the certificate; the item arrives damaged or with manufacturing defects; the wrong item was shipped. A return request must be filed within seven (7) calendar days of signed delivery, accompanied by clear photo and video evidence, and the item must be returned in its original packaging with all certificates, tags, and accessories intact.

3.4. Returns NOT Accepted. We do not accept returns or refunds based on personal aesthetic preference (you “expected a different look”); ring or band sizing that does not fit (sizing is the customer’s responsibility; we offer one complimentary re-sizing within twelve (12) months for standard designs); comparison with a competitor’s price or design; buyer’s remorse after a custom order has entered production; or normal physical characteristics described in Section 2.4.

3.5. Production Timelines Are Estimates. Lab-grown diamond custom-production lead times (typically 14–35 business days depending on complexity) and cross-border transit (typically 5–18 business days) are estimates only. Delays caused by laboratory grading backlogs, customs inspection, public holidays, weather events, carrier disruptions, geopolitical events, or force majeure are not grounds for cancellation, refund, or compensation.

3.6. Chargeback Abuse. Filing a fraudulent, retaliatory, or factually incorrect chargeback with your card issuer or payment platform is a violation of this Agreement and may trigger civil recovery, account termination, and referral to the payment processor’s fraud-prevention unit. We retain grading reports, laser-inscription records, factory production photos, quality-control videos, carrier tracking, and signature-on-delivery evidence for at least twenty-four (24) months to defend legitimate transactions.

Section 4 — Authenticity, Warranty, Care & Value Disclaimer

4.1. Independent Re-Verification Welcome. You are welcome to take any Tailor Diamonds stone to a reputable independent gemological laboratory (GIA, IGI, HRD, NGTC, or your local equivalent) for verification within thirty (30) days of delivery. If the independent report identifies a material discrepancy with our disclosed 4C parameters, we will refund the full purchase price plus reasonable documented third-party verification costs (capped at USD 150 / HKD 1,200) and arrange return shipping at our expense.

4.2. No Investment, No Guaranteed Resale Value. Tailor Diamonds makes no representation or promise that laboratory-grown diamonds will appreciate in value, retain their purchase price, or be repurchased at any future price. The market for loose lab-grown diamonds is evolving, opaque, and not liquid. You should treat your purchase as a decorative jewellery acquisition, comparable to fine fashion accessories, not as a financial instrument, store of value, retirement asset, or inflation hedge.

4.3. Manufacturing Warranty. We provide a lifetime manufacturing warranty against prong failure, setting defects, and stone loss under normal wear within the first twelve (12) months. After twelve (12) months, repair labour is complimentary; material and shipping costs apply. Warranty becomes void if the item has been resized, repaired, or modified by a third party not authorised in writing by Tailor Diamonds.

4.4. Not Covered by Warranty. The following are explicitly excluded from warranty coverage: loss of accent stones under 0.02 carat after 90 days; damage from impact, dropping, crushing, or improper storage; chemical damage from chlorine, bleach, perfume, or household cleaners; scratches, abrasion, or metal wear from daily use; unauthorised resizing, stone resetting, or jewellery modification; theft, loss, or disappearance after delivery is signed for.

4.5. Material Hardness vs. Brittleness. Lab-grown diamonds have the same Mohs hardness 10 as natural diamonds; however, they share the same cleavage and brittleness characteristics. Hard blows at certain angles can chip or fracture the stone. Wearing a diamond ring during heavy manual labour, contact sports, gardening, or swimming is done at the customer’s own risk and is not covered by warranty.

Section 5 — Cross-Border Shipping, Customs, Duties & Sanctions Compliance

5.1. Customer Bears Destination-Side Costs. The Website displays product prices that are typically DDP (Delivered Duty Paid) to selected major markets and DDU (Delivered Duty Unpaid) to other regions. Where DDU applies, you are solely responsible for paying destination-country import duties, value-added tax (VAT), goods and services tax (GST), customs clearance fees, inspection fees, demurrage, and any penalties imposed by your local customs authority.

5.2. Distinct HS Code Disclosure. In major markets, laboratory-grown diamonds are classified under distinct Harmonised System (HS) tariff codes that differ from natural diamonds, for example HS 7104.91 (laboratory-grown) versus HS 7102 / 7103 (natural) in many jurisdictions. We declare the goods accurately on the commercial invoice, customs declaration, and certificate of origin. You agree not to request, suggest, or pressure us to misdeclare, undervalue, hide, or omit the lab-grown nature of the goods on any shipping or customs document.

5.3. Consequences of Mis-declaration. If you (or your nominated freight forwarder, broker, or import agent) request under-valuation, mis-classification, or concealment of the lab-grown nature of the shipment, and the shipment is subsequently seized, detained, returned, destroyed, or fined by customs, all losses — including the value of the goods, shipping charges, return costs, storage fees, and any administrative penalty — are borne entirely by you, and we reserve the right to refuse future service.

5.4. Sanctioned-Origin Restriction. In compliance with multiple national sanctions regimes, we do not source, polish, set, re-export, or facilitate the sale of any laboratory-grown diamond that originated from, was processed in, or transited through a sanctioned jurisdiction, including rough or polished stones of Russian, Iranian, North Korean, or Myanmar origin, even if those stones are otherwise lawful in their country of production. We require full chain-of-warranty documentation from our cutting and polishing partners.

5.5. Material & Safety Compliance. All metal alloys used in Tailor Diamonds settings comply with REACH (EU), California Proposition 65, the U.S. Consumer Product Safety Improvement Act (CPSIA), and equivalent regulations on lead, cadmium, nickel release, and plasticiser content. Precious-metal stamping (Au 750 / Pt 950 / S 925) follows the relevant hallmarking or fineness law of the country of import.

5.6. Address Accuracy & Failed Delivery. You are responsible for providing a complete, accurate, and attended shipping address, including unit/floor numbers, door codes, and reachable contact phone number. Failed deliveries due to incorrect address, refusal to sign, prolonged absence, or inability to clear customs are not grounds for refund. Re-shipment, return-to-sender, and storage fees will be charged to you.

Section 6 — Intellectual Property, Brand Assets & Prohibited Conduct

6.1. Our IP. All content on the Website — including product photography, hand-drawn design renderings, video, 3D models, technical drawings, brand name “Tailor Diamonds”, the “TD” monogram, marketing copy, this Agreement, and our grading methodology — is the intellectual property of Tailor Diamonds Limited or its licensors and is protected by copyright, trademark, design right, and trade-secret law.

6.2. Limited Licence to You. You may view, save, and print Website content for personal shopping decisions, gift reference, or sharing with your own advisor. You may not copy, republish, sell, sub-license, data-mine, train AI models on, or commercially exploit any Website content, in whole or in part, without prior written consent.

6.3. No Misuse of Stone Data. The unique combination of carat, clarity, colour, cut, fluorescence, polish, symmetry, certification number, and laser inscription of each stone is itself proprietary information. You may not use this data to impersonate another customer, spoof a certificate, mislead a third party into believing a stone is natural, or create a competing listing.

6.4. Prohibited User Conduct. The following are grounds for immediate account suspension, order cancellation, and possible legal action: scraping, crawling, or harvesting Website data at scale; attempting to bypass purchase limits, security controls, or fraud detection; using stolen payment instruments or compromised accounts; opening multiple accounts to abuse promotions; posting defamatory, obscene, harassing, or hateful content in product reviews or customer-service channels; attempting to induce, bribe, or coerce our staff into disclosing confidential information.

6.5. Resale & Anti-Diversion. Tailor Diamonds products are intended for end-consumer personal use, gifting, or institutional corporate gifting. Wholesale, re-sale on third-party marketplaces, drop-shipping, or cross-border re-export for commercial purposes requires a separate written commercial agreement with Tailor Diamonds. Diversion in violation of this clause may result in account termination, voided warranty, and pursuit of liquidated damages.

Section 7 — Liability, Indemnity, Dispute Resolution & Final Provisions

7.1. Limitation of Liability. To the maximum extent permitted by applicable law, our aggregate liability arising out of or related to any single order shall not exceed the total amount you actually paid for that order. We are not liable for indirect, incidental, special, consequential, or punitive damages, including lost profits, lost savings, lost opportunity, or emotional distress, even if we were advised of the possibility of such damages.

7.2. Indemnity. You agree to indemnify, defend, and hold Tailor Diamonds, its directors, officers, employees, agents, and affiliates harmless from any third-party claim, demand, loss, liability, damage, or expense (including reasonable legal fees) arising out of your breach of this Agreement, your misuse of the Website, your violation of any law, or your infringement of any third-party right.

7.3. Governing Law. This Agreement is governed by, and construed in accordance with, the laws of the Hong Kong Special Administrative Region of the People’s Republic of China, without regard to its conflict-of-laws principles.

7.4. Friendly Negotiation First.

7.5. International Commercial Arbitration. If negotiation fails, the Dispute shall be finally settled by arbitration administered by the Hong Kong International Arbitration Centre (HKIAC) under the HKIAC Administered Arbitration Rules in force when the Notice of Arbitration is submitted. The seat of arbitration shall be Hong Kong. The number of arbitrators shall be one (1). The arbitration proceedings shall be conducted in English and Chinese, with the award rendered in both languages. The arbitral award shall be final and binding on both parties and may be enforced in any court of competent jurisdiction under the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958).

7.6. Consumer-Rights Carve-Out. Nothing in this Agreement is intended to override mandatory consumer-protection rights granted to you by the laws of your country of habitual residence, including any non-derogable right of withdrawal, refund, or redress. Where local law provides stronger protection than this Agreement, that local law prevails for that specific issue.

7.7. Severability. If any provision of this Agreement is held by a court or tribunal of competent jurisdiction to be invalid, illegal, or unenforceable, that provision shall be severed and the remaining provisions shall continue in full force and effect.

7.8. No Waiver. Our failure to enforce any right or provision of this Agreement shall not constitute a waiver of that right or provision, nor of any subsequent breach.

7.9. Entire Agreement. This Agreement, together with our Privacy Policy, Shipping & Delivery Policy, Returns Policy, and any order-specific confirmations, constitutes the entire agreement between you and Tailor Diamonds regarding the subject matter described and supersedes all prior or contemporaneous understandings, written or oral.

2.4. 正常物理属性。 不同光源下颜色的细微差异、火彩与闪烁的轻微变化、生长工艺相关的微弱金属包裹体、生长纹路以及浅蓝或浅黄色调均属 培育钻石固有物理属性，不 视为制造瑕疵，不 作为退换货理由。

2.5. 无隐匿处理。 我们不出售经过 未披露 镀膜、裂隙填充、净度改善激光打孔、颜色辐照或 HPHT 颜色退火的钻石。每颗钻艺钻石均按”原生长+完整披露”状态供应。

2.6. 拍摄说明。 商品图片在 5500K 日光色温受控光源下拍摄。由于屏幕校准、环境光、拍摄角度及后期处理存在差异，屏幕显示效果可能与实物略有出入。该视觉差异属正常现象，不构成”与描述不符”。

第三条 · 订单定制、生产与退换货规则

3.1. 定制生产。 我们目录中相当一部分商品——包括裸石选购、定制求婚戒指、定制结婚对戒、刻字吊坠、个性化耳饰及任何标注”Made to Order / 定制”的产品——均 根据您确认的参数（石料、贵金属、戒指尺寸、刻字内容、镶嵌款式） 专门为您生产。一旦生产启动，定金不可退、订单不可取消、7 天无理由退货权不适用，因定制商品对他客户无转售价值。

3.2. 现货未发货改单。 对于 尚未发货 的现货商品，您可以申请修改尺寸、刻字内容或更换为同等或更高价值的等价现货（价差由您承担）。我们将尽力配合，但一旦运单标签已生成，则无法保证修改。
