General Terms & Conditions

Diamantwerp is a family-run certified diamond dealer established in 1987, operating from the heart of the Antwerp Diamond District. We specialise exclusively in loose, certified natural diamonds.

In these General Terms & Conditions, the following terms shall have the meanings ascribed to them below:

• "Seller", "We", "Us", "Our": Diamantwerp, as identified in Article 1.
• "Buyer", "Customer", "You", "Your": Any natural or legal person who places an order through our website, by email, by telephone, or in person at our premises.
• "Consumer": A natural person acting for purposes outside their trade, business, craft, or profession, as defined by Article I.1, 2° of the Belgian Code of Economic Law.
• "Professional Buyer": A natural or legal person acting within the scope of their trade, business, craft, or profession.
• "Order": A request by the Customer to purchase one or more Products, constituting a binding offer once confirmed.
• "Product(s)": The loose natural diamonds and/or related goods offered for sale by Diamantwerp.
• "Agreement": The binding contract formed between Seller and Buyer upon confirmation of the Order.
• "Website": www.diamantwerp.be, including all subpages and the integrated webshop.
• "Working Day": Any day that is not a Saturday, Sunday, or Belgian public holiday.
• "Certificate": The independent gemological grading report issued by GIA, HRD Antwerp, or IGI accompanying each diamond.

These General Terms & Conditions apply to every offer, quotation, order, and agreement between Diamantwerp and the Customer, regardless of the channel through which the transaction is initiated (website, email, telephone, or in person), unless expressly agreed otherwise in a separate written agreement signed by both parties.

By placing an order, the Customer confirms that they have read, understood, and accepted these terms in full. These terms are made available to the Customer prior to the conclusion of any agreement and can be saved, printed, and reproduced at any time via our Website.

Any general terms or conditions of the Customer are hereby expressly excluded and shall not apply, even if they have not been explicitly rejected.

If any provision of these terms is held invalid or unenforceable by a competent court, the remaining provisions shall continue in full force and effect. The invalid provision shall be replaced by a valid provision that achieves the same commercial purpose as closely as legally permissible.

In the event of a conflict between these General Terms & Conditions and any specific written agreement, the specific written agreement shall prevail, but only to the extent of the conflict.

All products offered on our Website are described as accurately as reasonably possible, including diamond specifications such as carat weight, colour grade, clarity grade, cut grade, shape, and certification details. Product descriptions are based on the accompanying Certificate issued by an independent gemological laboratory.

Product images are indicative only. Photographs, videos, and other visual representations on the Website are intended to provide a general impression and may not reflect the exact visual appearance of the specific diamond being purchased. Natural diamonds are unique; minor variations in colour, inclusions, and light performance do not constitute a defect or non-conformity.

The Certificate accompanying each diamond shall be considered the definitive and binding specification document. Any claim regarding the characteristics of a purchased diamond shall be assessed exclusively with reference to the Certificate, not to Website imagery or descriptions.

Diamantwerp reserves the right to modify, update, or discontinue any part of its product range at any time without prior notice. The display of a product on the Website does not constitute a binding offer and is subject to availability. Obvious errors — including typographical errors — shall not bind the Seller.

5.1 Pricing

All prices displayed on the Website are in euros (€) and include VAT for consumers within Belgium, unless explicitly stated otherwise. For B2B transactions or international orders, VAT may be excluded, reverse-charged, or adjusted in accordance with applicable tax regulations.

Delivery costs, insurance fees, and any other applicable charges are clearly communicated before the order is finalised. The total price — including all taxes, duties, and charges — is displayed at checkout before confirmation.

Diamantwerp reserves the right to adjust prices at any time without prior notice. Price changes do not affect orders already confirmed. Diamond prices are subject to international market fluctuations.

5.2 Payment Methods

We accept the following payment methods:

• Bank transfer (SEPA): Payment must be received in full before the order is processed. A 1% discount applies to orders paid by bank transfer.
• Bancontact: Available for Belgian customers.
• Cash at our office: By prior appointment only, subject to Belgian legal limits.

5.3 Payment Terms

Payment is due in full prior to delivery. No Product shall be shipped or released until full payment has been received and verified. Title to and ownership of the Product(s) shall not pass to the Customer until payment is received in full (retention of title).

In the event of late payment, Diamantwerp reserves the right to: (a) charge interest at the statutory rate; (b) claim reasonable recovery costs; and (c) suspend or cancel the order without further obligation.

The ordering process on diamantwerp.be follows these steps:

1. The Customer selects a specific diamond — identified by its unique gemological certificate number (GIA, HRD, or IGI) — and adds it to the shopping cart.
2. The Customer reviews the order summary, including the certificate number, diamond specifications, total price, and any applicable exceptions to the right of withdrawal.
3. The Customer provides billing and shipping information and confirms the accuracy of all details provided.
4. The Customer selects a payment method.
5. The Customer reviews and accepts these General Terms & Conditions by ticking the designated checkbox, including any applicable exception to the right of withdrawal as described in Article 9.
6. The Customer confirms the order by clicking the order button, which constitutes a binding and irrevocable offer to purchase the specific diamond identified by its certificate number. By doing so, the Customer expressly acknowledges that this diamond has been individually selected and, where applicable, specifically sourced on their request.
7. The Customer receives an automated order acknowledgement via email, confirming the certificate number and specifications. This acknowledgement does not constitute acceptance of the order by the Seller.

The Agreement is formed only upon the Seller's explicit confirmation sent via a separate confirmation email. Diamantwerp reserves the right to refuse or cancel any order in case of suspected fraud, pricing errors, product unavailability, or failure to verify the Customer's identity. In such cases, any amounts already paid will be refunded in full within 14 calendar days.

The Customer is solely responsible for the accuracy of all information provided during the ordering process. Diamantwerp shall not be liable for any delay, loss, or additional cost resulting from incorrect information provided by the Customer.

7.1 Delivery Methods

• Insured courier delivery: Via a specialised, insured courier service. Delivery times and costs are communicated at checkout and in the order confirmation.
• Personal collection: At our office, Pelikaanstraat 62, 2018 Antwerp, by prior appointment only. The Customer must present valid photo identification upon collection. Note: our office is not a walk-in showroom. Collection is strictly by appointment.

7.2 Delivery Times

Estimated delivery times are communicated during the ordering process and in the order confirmation email. These are indicative only and do not constitute binding commitments. Unless otherwise agreed, delivery shall take place within 30 calendar days of order confirmation, in accordance with Article VI.43 of the Belgian Code of Economic Law.

If Diamantwerp is unable to deliver within the agreed timeframe, we shall notify the Customer without undue delay and offer the option of: (a) a revised delivery date; or (b) cancellation of the order and a full refund.

7.3 Risk Transfer

For Consumers: the risk of loss or damage to the Product passes to the Customer upon physical receipt of the goods, in accordance with Article VI.44 of the Belgian Code of Economic Law.

For Professional Buyers: the risk passes to the Customer upon handover of the Product to the first carrier, unless otherwise agreed in writing.

All shipments are fully insured for the declared value of the diamond(s) during transit. Once the Customer has signed for receipt, all risk — including loss, theft, and damage — passes irrevocably to the Customer.

7.4 Delivery Area & Customs

Diamantwerp delivers within Belgium, the European Union, and selected international destinations. Delivery options and costs may vary by destination.

For deliveries outside the European Union, the Customer is solely responsible for all import duties, customs taxes, and any other levies imposed by the destination country.

8.1 Withdrawal Period

The withdrawal period of 14 calendar days begins the day after the Consumer takes physical possession of the goods.

This right of withdrawal applies exclusively to Consumers as defined in Article 2. Professional Buyers do not benefit from this right.

8.2 How to Exercise the Right

To exercise the right of withdrawal, the Customer must inform Diamantwerp by means of an unambiguous written statement before the withdrawal period expires. This can be done by:

• Email to: questions@diamantwerp.be
• Registered letter to: Diamantwerp, Pelikaanstraat 62, 2018 Antwerp, Belgium
• Using the model withdrawal form (available upon request)

Timely dispatch of the withdrawal notification is sufficient — the Customer is not required to have returned the goods before the withdrawal period expires. The burden of proof rests with the Customer.

8.3 Return Conditions

The Customer must return the Product(s) no later than 14 calendar days after communicating the withdrawal. The Product must be returned:

• In its original, unopened, and undamaged condition
• With all original certifications (GIA, HRD, IGI) included
• In the original packaging, with all security seals intact
• With no signs of wear, use, or alteration beyond what is strictly necessary to examine the product

The Customer bears the direct cost of returning the goods. Given the high value of our Products, we strongly recommend and may require the use of an insured and traceable shipping method.

8.4 Inspection & Diminished Value

Upon receipt of the returned Product, Diamantwerp reserves the right to conduct a thorough inspection by a qualified gemologist to verify the identity, condition, and integrity of the diamond against the original Certificate. This inspection may take up to 5 working days.

If the returned Product shows signs of use, damage, or tampering beyond what is strictly necessary, Diamantwerp may reduce the refund amount proportionally to reflect the diminished value, in accordance with Article VI.51 §3 of the Belgian Code of Economic Law.

8.5 Refund

If the return is accepted, Diamantwerp will reimburse all payments received from the Customer, including standard delivery costs, within 14 calendar days of receiving the returned Product or proof of dispatch, whichever is earlier.

Diamantwerp may withhold the refund until the Product has been received and inspected. The refund is made using the same payment method as the original transaction. No additional charges are applied.

For full details on our return procedures, please refer to our Refund & Return Policy.

In accordance with Article VI.53 of the Belgian Code of Economic Law, the right of withdrawal shall not apply in the following circumstances. Where one or more exceptions apply, this is clearly communicated to the Customer before the order is confirmed.

9.1 Market-Linked Pricing

The right of withdrawal does not apply to products whose price is dependent on fluctuations in the financial market that the Seller cannot control, and which may occur within the withdrawal period (Article VI.53, 2° of the Belgian Code of Economic Law).

Natural diamond prices are determined by international wholesale market indices — in particular the Rapaport Price List and live trading platforms (Rapnet) — which fluctuate continuously based on global supply, demand, currency movements, and macroeconomic factors. Diamantwerp sources diamonds at market prices that are live at the time of purchase.

9.2 Individually Sourced Diamonds — Purchased on Specific Request

The right of withdrawal does not apply to products that have been made or procured to the Consumer's specifications or that are clearly personalised (Article VI.53, 3° of the Belgian Code of Economic Law).

Each diamond listed on diamantwerp.be is a unique, individually identified product bearing its own gemological certificate number issued by GIA, HRD Antwerp, or IGI. When a Customer selects a specific diamond — identified by its unique certificate number — and places an order, Diamantwerp reserves and, where necessary, specifically procures that individual stone from its wholesale network on behalf of the Customer.

• The diamond purchased is not an interchangeable stock item but a uniquely identified product selected by the Customer, identified by a specific certificate number confirmed in the order.
• Where Diamantwerp has specifically procured the diamond from a third-party supplier upon receipt of the Customer's order, that procurement is made exclusively on the Customer's behalf and cannot be reversed with the original supplier (wholesale B2B transactions are final).
• The Customer's express selection of the specific certificate number constitutes a clear personalisation of the order within the meaning of Belgian consumer law.

9.3 Custom Jewellery & Bespoke Products

The right of withdrawal does not apply to products that are custom-made or clearly personalised to the Customer's specifications. This includes, without limitation:

• Bespoke jewellery settings: any ring, pendant, bracelet, or other jewellery item manufactured or assembled to the Customer's specifications (metal type, ring size, design, engraving, etc.).
• Diamond-in-setting combinations: where a loose diamond is set into a jewellery mount at the Customer's request, the resulting piece is a custom product and fully exempt from the right of withdrawal.
• Engraved or otherwise personalised products.

For bespoke orders, Diamantwerp will provide a written order specification prior to production. The Customer's written approval of the specification constitutes final confirmation and waiver of the right of withdrawal.

9.4 Sealed Products Unsealed After Delivery

Where a product is delivered in sealed packaging and the Customer has broken the seal after delivery, the right of withdrawal does not apply if the product cannot be returned for reasons of authenticity verification or security.

10.1 Legal Guarantee

In accordance with Articles 1649bis to 1649octies of the Belgian Civil Code and EU Directive 2019/771 on the sale of goods, the Consumer benefits from a legal guarantee of conformity for a minimum period of two years from the date of delivery.

This means Diamantwerp guarantees that the diamond delivered corresponds to the description, quality, and specifications as stated in the order confirmation and the accompanying Certificate.

10.2 Non-Conformity

If the delivered Product does not conform to the Agreement, the Customer must notify Diamantwerp as soon as reasonably possible after discovering the defect, and in any event within two months of discovery.

For defects apparent within one year of delivery, it is presumed that the lack of conformity existed at the time of delivery (reversal of burden of proof). The Customer may request, in order of priority:

1. Repair or replacement of the Product (where possible and proportionate)
2. A proportionate reduction in price
3. Termination of the Agreement and a full refund

Diamantwerp will respond to any conformity claim within 10 working days and will cover all reasonable costs associated with a justified return, replacement, or refund.

10.3 Exclusions

The legal guarantee does not cover:

• Defects caused by misuse, negligence, improper storage, or failure to follow care instructions
• External damage caused by accidents, impacts, or exposure to chemicals or extreme temperatures
• Normal wear and tear
• Modifications or repairs made by the Customer or any third party not authorised by Diamantwerp
• Defects that were known to or should reasonably have been noticed by the Customer at the time of purchase

For Professional Buyers, the legal guarantee is limited to the mandatory minimum under Belgian law.

Every diamond sold by Diamantwerp is accompanied by an independent grading Certificate from one or more of the following internationally recognised gemological laboratories:

• GIA — Gemological Institute of America
• HRD Antwerp — Hoge Raad voor Diamant
• IGI — International Gemological Institute

The Certificate provides an objective assessment of the diamond's characteristics (carat, colour, clarity, cut) and serves as proof of authenticity and the definitive specification of the Product.

We guarantee that all diamonds sold are 100% natural and conflict-free, in full accordance with the Kimberley Process Certification Scheme and the World Diamond Council's System of Warranties.

Diamantwerp does not accept returns of diamonds not accompanied by the original, unaltered Certificate. Any claim regarding the conformity or characteristics of a diamond will be assessed exclusively with reference to the accompanying Certificate.

Disclaimer: Grading by GIA, HRD, or IGI is conducted by those respective organisations. While these laboratories are internationally recognised and highly reputable, minor variations between laboratories or between evaluations are inherent to the process. Diamantwerp does not guarantee any specific grading outcome by a laboratory other than the one that issued the original Certificate.

Diamantwerp is liable for damages resulting from a failure to fulfil its contractual obligations, in accordance with Belgian law and subject to the limitations set out in this article.

12.1 Maximum Liability

Without prejudice to mandatory legal provisions, Diamantwerp's total aggregate liability for any and all claims arising from or in connection with an order shall not exceed the purchase price actually paid by the Customer for the specific Product(s) giving rise to the claim.

12.2 Exclusion of Indirect Damages

To the maximum extent permitted by law, Diamantwerp shall not be liable for any:

• Indirect, incidental, special, or consequential damages
• Loss of profit, revenue, business, or anticipated savings
• Loss of data or corruption of data
• Loss of goodwill or reputation
• Emotional distress or non-material damages (except where mandatory under Belgian law)
• Damages arising from the Customer's inability to use or resell the Product

12.3 Specific Exclusions

Diamantwerp is not liable for:

• Damage resulting from the Customer's failure to follow care, storage, or handling instructions
• Damage, loss, or theft of diamonds after risk transfer to the Customer (see Article 7.3)
• Any decrease in the market value of diamonds after purchase
• Errors or inaccuracies in information provided by the Customer
• Third-party actions, including customs authorities, payment processors, and courier services
• Temporary unavailability or technical issues with the Website

12.4 Force Majeure

Diamantwerp is not liable for any delay or failure in performance resulting from circumstances beyond its reasonable control (force majeure), including but not limited to: natural disasters, pandemics, war, terrorism, government sanctions, trade embargoes, supply chain disruptions, carrier failures, or cyberattacks.

If the force majeure event continues for more than 60 calendar days, either party may terminate the Agreement in writing, and any amounts paid shall be refunded in full.

12.5 Consumer Rights

These limitations do not affect the Consumer's mandatory statutory rights under Belgian law, including the legal guarantee as described in Article 10 and the right of withdrawal as described in Article 8.

In accordance with EU Regulation 524/2013, Consumers may also submit complaints via the European Commission's Online Dispute Resolution platform: ec.europa.eu/consumers/odr

Submission to any mediation or ODR procedure shall not affect either party's right to bring proceedings before the competent courts as described in Article 16.

These General Terms & Conditions and any agreement between Diamantwerp and the Customer shall be governed by and construed in accordance with Belgian law, without regard to its conflict of law provisions.

Any disputes arising from or in connection with these terms, any order, or any agreement shall be submitted exclusively to the competent courts of Antwerp, Belgium.

The foregoing choice of jurisdiction does not affect the Consumer's right to bring proceedings in the courts of their place of domicile, nor does it affect the Consumer's right to invoke the protection of mandatory consumer protection provisions of their country of habitual residence, in accordance with EU Regulation 593/2008 (Rome I) and EU Regulation 1215/2012 (Brussels Ibis).

Diamantwerp reserves the right to amend these General Terms & Conditions at any time. Amendments take effect upon publication on the Website and do not affect orders already confirmed prior to the date of publication.

For material changes that significantly affect the Customer's rights or obligations, Diamantwerp shall endeavour to provide reasonable notice.

The most recent version of these terms is always available on our Website at diamantwerp.be/general-terms-and-conditions. Continued use of the Website after publication of amended terms constitutes acceptance of the amended terms.

If any provision of these General Terms & Conditions is found to be invalid, unlawful, or unenforceable, the validity and enforceability of the remaining provisions shall not be affected. The invalid provision shall be replaced by a valid provision that most closely reflects the economic intent and purpose of the original provision.

The date of the most recent revision is displayed at the top of this page.
