Question 1

How much are second-hand gold chains worth?

Accepted Answer

Gold chains usually sell close to their scrap value plus a small premium. Check the weight and hallmark on the advert, look up the day's gold price per gram, and expect to pay roughly 10–30% above melt value for a wearable chain in good condition.

Question 2

What length necklace should I buy?

Accepted Answer

The most popular lengths are 16 inches (sits at the collarbone), 18 inches (just below, the standard for pendants) and 20–24 inches for a longer drop. Sellers on JewelleryTrader list chain length on the advert — measure a necklace you already like wearing to compare.

Question 3

How do I check a hallmark is genuine?

Accepted Answer

A genuine UK hallmark is struck (or laser-marked) by one of the four UK Assay Offices — London, Birmingham, Sheffield or Edinburgh — and shows the metal, its fineness, the assay office mark and usually a date letter and sponsor's mark. Compare the marks on the item with the reference tables published by the Assay Offices, and ask the seller for a clear close-up photo. A hallmark that is blurred, misspelt or in the wrong place is a red flag.

Question 4

How do I avoid scams when buying necklaces online?

Accepted Answer

View the item in person before any money changes hands — or use a reputable escrow for high-value pieces — keep all messages inside JewelleryTrader so there is a record, and never pay by bank transfer, gift card or crypto to someone you have not verified. For precious metal, always check the hallmark against the Assay Office records, and for certified stones verify the certificate number directly with GIA or IGI. Every JewelleryTrader seller completes a photo-ID and live selfie check, verified accounts carry a badge, and you can report an advert from the listing page.

Question 5

How do I know what my jewellery is worth before selling?

Accepted Answer

Get an independent valuation first — many high-street jewellers value items for a small fee, and the Institute of Registered Valuers keeps a directory of accredited valuers. Then compare live asking prices for similar pieces on JewelleryTrader so your price reflects what buyers are actually paying. Remember that insurance (replacement) valuations are usually two to three times what a piece will sell for second-hand.
