How to Run an Online Jewelry Auction
Rings, watches, loose stones and estate jewelry sell online when buyers can trust the description as much as they would trust their own loupe. This guide covers how to present each piece, protect the sale and get it safely to the winner.

Know what you are selling
Test metals and identify stones before anything is listed. For diamonds and important coloured stones, an independent grading report from a recognised laboratory makes a large difference to the price. Record hallmarks and makers’ marks, and weigh each piece.
Describe each piece fully
- Metal and fineness, total weight and ring size or length.
- Stones: type, carat weight and, for diamonds, colour, clarity and cut — with the report number where there is one.
- Watches: maker, model, reference, movement, and whether box and papers are included and it has been serviced.
- Condition: wear, repairs, replaced parts, and anything untested.
Link the certificate
Photograph the grading certificate and link to the report on the laboratory’s own website, where many labs let anyone look a report up by its number. A buyer who can check the report independently bids with more confidence than one who has to trust a scan.
Photograph under the right light
Use diffused daylight or daylight-balanced lamps, a plain background and a macro lens or setting. Show the piece from the front, the side and the back, the hallmarks, the clasp and the stones close up. Do not edit colour — a stone that looks better online than in the hand comes back.
Reserves and closing times
Set reserves on significant pieces and let smaller lots start low. Close lots a couple of minutes apart and use soft close, so a late bid extends the clock. Let buyers leave a maximum bid in advance if they cannot watch the close.
Protect the sale
Know who your consignors are and where their pieces came from; in many countries dealers must take extra care with second-hand jewelry and high-value cash transactions. Require bidders to register, and on valuable lots require a card on file before bidding. For a private sale, keep the catalogue behind an access code.
Payment and insured shipping
Take payment in full before shipping. Send jewelry by a tracked, insured service and state the delivery charge on each lot; for high-value pieces, offer collection in person. Say in your terms when risk passes to the buyer.
Frequently asked questions
Do I need a grading report to auction a diamond?
It is not always required, but for any significant stone an independent report from a recognised laboratory usually raises the price considerably, because buyers can rely on it.
How do I photograph jewelry for an online auction?
In diffused daylight or daylight-balanced light, against a plain background, with close-ups of stones, hallmarks and the clasp, and without editing the colour.
How should jewelry be shipped after an auction?
By a tracked and insured service, only after full payment, with the delivery charge and the point at which risk passes to the buyer stated in your terms.
How do I avoid bidders who never pay?
Require registration and, on valuable lots, a card on file before bidding; state the payment deadline in your terms and ship only after payment.
