Show your licence number if you need one
Anyone selling rings as a business must trade honestly and follow the Hallmarking Act 1973 — items over the exemption weight must carry a valid UK hallmark before they can be described as gold, silver or platinum. Any trading name and business details required by consumer law must appear in the advert itself.
Give the size, metal and hallmark
State the UK finger size, the metal and its fineness (9ct, 18ct, 950 platinum), and describe the hallmark including the assay office mark and date letter. Say whether the ring has been resized before, as that can affect the shank and any hallmark.
Back up diamond and gemstone claims
If you quote a carat weight, colour or clarity, say where it comes from — a GIA, IGI or AGS certificate, an independent valuation, or your own estimate. Photograph the certificate number and include it in the advert.
Use real, recent photographs
Stock images and photos lifted from elsewhere online are the number one sign of a scam advert. Pictures must be of the actual item you are selling, showing its true condition. Adverts using images found elsewhere are removed.
Describe health and history honestly
Metal, purity, stones, condition and any repairs all belong in the advert. Under the Consumer Rights Act a buyer can come back to you if the item was misdescribed, so being straight up front protects you as well as them.
Verify who you are
JewelleryTrader will not publish an advert until the seller has passed an identity check — photo ID matched against a live selfie. It takes a couple of minutes and it is the main reason buyers trust adverts here over free classified sites.
