7. Delivery and Reception
7.1 Delivery Methods, Address and Confidentiality: Products are delivered exclusively to the address provided by the Buyer. For security reasons, the delivery address must match the Buyer’s identity (surname and first name).
-
In Switzerland: From 0 to 5,000 CHF via Swiss Post (Insured & Signature). From CHF 5,000 to CHF 15,000 via Malca-Amit via FedEx. Over CHF 15,000 via Malca-Amit only.
-
International and Europe: Shipments are entrusted to Malca-Amit, guaranteeing secure delivery via their own networks or via FedEx under the direct liability of Malca-Amit.
-
Discretion: The sender listed on the parcel is Dodeca Partners Sàrl. No reference to the contents or the brand appears on the outer packaging. No deliveries to PO boxes or ‘c/o’ addresses.
7.2 Insurance and Liability: Each consignment is fully covered by specialist insurance managed by Malca-Amit, corresponding to 100% of the actual invoice value. Malca-Amit assumes liability for transit, thereby exempting the customer from any financial loss, subject to compliance with verification procedures. The reference to “Zurich Insurance” has been removed from our protocols in favour of direct liability on the part of the cash-in-transit company Malca-Amit.
7.3 Delivery Terms and Security: A handwritten signature and presentation of an official identity document in the Buyer’s name are mandatory. Dodeca Diamonds reserves the right to arrange for delivery to be made personally by the Management.
7.4 Delivery times: Standard delivery times are 5 to 8 working days for Switzerland and 7 to 15 working days for international deliveries following confirmation of payment.
7.5 Tracking and Indemnity Clause: The customer can track their shipment in real time. Any instruction to ‘leave without signature’ or ‘leave at the entrance’ given unilaterally by the customer to the carrier results in Dodeca Diamonds being fully released from liability. In such cases, the transport insurance cannot be activated.
7.6 Customs charges and import formalities: For deliveries outside Switzerland, products are invoiced exclusive of VAT. All customs formalities, local VAT and import duties are the sole responsibility of the Buyer.
7.7 Obligations upon receipt (Art. 185 & 201 CO): Notwithstanding Art. 185 CO, the transfer of risk shall only take place upon actual delivery against signature. The customer must check the integrity of the packaging and the seal in the presence of the carrier. If the seal is broken, the customer must refuse the delivery and inform the Seller within 24 hours.
8. TRANSFER OF OWNERSHIP AND RISK
8.1 Transfer of Ownership : Ownership is transferred to the customer only after full payment of the price, regardless of the delivery date.
8.2 Transfer of Risk : Risk is transferred when the customer, or a designated third party, takes physical possession of the package (as evidenced by a handwritten signature). In the case of a drop-off instruction without a signature (Art. 7.5), risk is transferred upon delivery by the carrier.
9. Specific Orders and Customized Withdrawal Protocols
9.1 Scope : This clause applies exclusively to stones whose description or order confirmation expressly mentions a "right of return." This applies to any order specifically sourced at the Client's request (excluding stones physically present in Switzerland) or available on our website, and for which full payment has been received in advance.
9.2 Selection and Confirmation of Delivery Method : When ordering online, the Customer chooses their delivery method. This choice is systematically revalidated by Dodeca Diamonds during the order confirmation contact. Hand delivery is made either on the Riviera (VD), or via personalized delivery within Switzerland by Dodeca Diamonds Management (depending on the order amount and the customer relationship).
9.3 Inspection and Final Acceptance (pursuant to Art. 201 of the Swiss Code of Obligations): Upon personal delivery, the Client shall inspect the stone (the Client may, at their own expense, request the presence of their own expert). In accordance with Article 201 of the Swiss Code of Obligations, physical possession or signing of the delivery note constitutes acceptance of the goods and final approval. No claims for apparent defects or returns for personal reasons will be accepted after delivery.
9.4 Cancellation during inspection : If the Client decides, during the physical inspection only, not to finalize the purchase for reasons of personal convenience (justified by a serious reason), the sale may be cancelled on the spot. Dodeca Diamonds reserves the right to refuse any future transactions in the event of clear abuse or repeated cancellations (principle of good faith, Art. 2 CC), and may claim compensation for any damages incurred.
9.5 Liability for logistical costs (pursuant to Art. 189 of the Swiss Code of Obligations): In the event of cancellation as described in point 9.4, the Customer remains, by agreement contrary to the meaning of Article 189 of the Swiss Code of Obligations, fully liable for the costs incurred. The refund of the purchase price will be made after deduction of the actual logistical costs: secure international transport (to Switzerland and back to the original supplier), transit insurance costs, as well as non-refundable customs duties and taxes.
10. RIGHT OF WITHDRAWAL AND RETURNS
10.1 No statutory right of withdrawal (Swiss law): In accordance with Swiss law, the right of withdrawal does not apply to diamonds and precious stones sold by Dodeca Diamonds Switzerland, due to their unique nature and value. Any request for a return or refund must first be accepted in writing by Dodeca Diamonds Switzerland. No withdrawal will be possible without the company’s explicit consent. As a matter of commercial courtesy, the Seller will only consider a return for products with a proven defect or total non-conformity with the certificate of authenticity provided.
10.2 Items strictly excluded from return and refund: In accordance with standard practice in the high-end gemmology sector, no returns, exchanges or refunds will be accepted for:
• Products made to specific order: Stones sourced specifically at the Buyer’s request.
• Personalised creations: Any piece of jewellery made to measure, engraved, cut to size or modified on request.
• Product alteration: Stones cut or modified after delivery, products showing signs of wear, assembly or testing.
• Broken seal: Any product whose security seal (laboratory box or Dodeca seal) has been broken or opened.
• Documentation: Any item for which the original certificate of authenticity or specific packaging has been lost or damaged.
10.3 Return Policy (Stock Items Only): For standard products held in stock at our warehouse in Switzerland, a return request may be considered subject to the following conditions:

10.3.3 Condition of the product: The item must be returned unused, in its exact original condition, with its case and original certificate of authenticity.

10.4 Refund procedure: * Verification: Upon receipt of the returned item, our gemmologist will carry out an assessment (checking the laser inscription, inclusions and weight) to confirm that the stone matches the one sold. If the assessment is satisfactory, the refund will be processed via the same payment method within 10 working days, less any non-refundable bank transaction fees.
-
Rejection: If the return is rejected (failure to meet the above conditions), the item will be returned to the Buyer at their sole expense.
10.5 Nature of the products: The Buyer acknowledges that stones, crystals and minerals are natural products that frequently contain inclusions, cracks or cavities. These characteristics form part of the item’s identity and do not constitute valid grounds for a return. Only proven non-conformity with the certificate of authenticity (GIA, HRD, IGI) may justify a return.
11. GUARANTEE, AUTHENTICITY AND CONFORMITY
11.1 Certifications and Authenticity: Dodeca Diamonds Switzerland is committed to selling only diamonds and gemstones of the highest quality. Each item (weight ≥ 0.15 ct) is accompanied by an original certificate of authenticity (GIA, HRD or IGI) guaranteeing the authenticity, provenance and specific characteristics of the product. The Buyer acknowledges that this certificate constitutes an authoritative independent appraisal.
11.2 Guarantee of Conformity (Art. 197 CO): The Seller guarantees that the product delivered corresponds in every respect to the description in the certificate and the order confirmation. These provisions shall in no way deprive the Buyer of the statutory guarantee provided for by the Swiss Code of Obligations, which requires the professional seller to guarantee the buyer against hidden defects.
11.3 Distributor Status and Limitation: The Buyer is hereby informed that Dodeca Diamonds Switzerland is not the manufacturer (cutter or producer) of the products offered and shall not be held liable for any damage resulting from defective products beyond the certified specifications. Unless expressly stated otherwise, no other contractual warranty applies.
11.4 Ethical Origin Guarantee: We declare that we strictly adhere to the Kimberley Process and United Nations resolutions, guaranteeing that all our diamonds come from legitimate ‘Conflict-Free’ sources, not involved in the financing of armed conflicts.
11.5 Natural Characteristics and Exclusions: The Buyer is advised that the natural characteristics of the stones (inclusions, marks, natural fissures), as detailed in the ‘Product Characteristics’ section, form an integral part of their identity and value; they do not constitute a defect. The warranty also excludes:
-
Natural wear and tear, loss, theft or accidental breakage after the transfer of risk.
-
Any damage resulting from improper handling or negligence.
-
Third-party intervention: Any damage resulting from the intervention of an unauthorised third party (e.g. setting error or alteration by an external jeweller) shall release the Seller from all liability.
11.6 Duty to inspect and notification of defects (Art. 201 CO): In accordance with Swiss law, the Buyer is obliged to inspect the condition of the stone upon receipt.
• Time limit: If the Buyer discovers any defects or non-conformities, they must notify the Seller immediately, and in any event within 48 hours.
• Acceptance: In the absence of such notification within this time limit, the item is deemed to have been accepted by law, except in the case of hidden defects that cannot be detected during the usual checks.

In any event, its liability is strictly limited to the amount of the order actually received.
