Auction rules & terms.

The following terms govern all OPIKJEWELS live and online auctions. Registration to bid constitutes acceptance of these terms.

1 · Registration

All bidders must complete identity verification (KYC) and have an active OPIKJEWELS account. Bidders for lots with a low estimate above USD 50,000 must provide a financial reference or refundable deposit of 10% of the low estimate before bidding privileges are activated.

2 · Bid increments

Bids advance in increments scaled to the current price level. Indicative scale:

• Below USD 5,000 — USD 200
• USD 5,000 – 20,000 — USD 500
• USD 20,000 – 100,000 — USD 2,000
• USD 100,000 – 500,000 — USD 10,000
• Above USD 500,000 — USD 25,000

The auctioneer retains discretion to vary increments to maintain pace.

3 · Reserve

Most lots are offered subject to a confidential reserve — the minimum price the consignor will accept. The reserve never exceeds the published low estimate. Lots that fail to meet reserve are "passed" and may be re-offered, sold post-auction at negotiated terms, or returned to the consignor.

4 · Buyer's premium

A buyer's premium of 22% is added to the hammer price, applicable to all lots. The premium covers cataloguing, gemological verification, photography, marketing, and platform infrastructure. The published catalogue estimate excludes buyer's premium.

5 · Settlement

Successful bidders must settle within 7 calendar days of the hammer. Accepted methods: bank wire (Bank Mandiri Jakarta or Bangkok counterparties), Stripe for amounts under USD 50,000. Title transfers only on cleared funds.

6 · Final sale

All auction sales are final. The standard 7-day return policy applicable to inventory listings does not apply to lots won at auction. The Lifetime Authenticity Guarantee (see Authenticity policy) continues to apply.

7 · Dispute resolution

Any dispute is governed by the laws of the Republic of Singapore and subject to arbitration under the rules of the Singapore International Arbitration Centre (SIAC) in Singapore, in English, by a sole arbitrator.
