Sell a mixed jewellery box by post — UK-wide

A surprising share of the gold value sitting in UK homes is in mixed jewellery boxes rather than identifiable single pieces. A drawer cleared after a house move; a jewellery box inherited from a parent and never sorted; a collection of single earrings whose pairs have been lost over decades. The contents typically include a mix of real 9ct gold, real 18ct gold, real silver, costume jewellery, plated brass, single gemstones and the occasional surprise (a sovereign in a cufflink, a 22ct bangle at the bottom).

Most people do not know what is real gold and what is plated. The carat markings, where they exist, are tiny and worn; many pieces have no marking at all. The mixed-box postal service exists precisely for this: post the whole box, we sort it on arrival, identify which pieces are real precious metal and which are not, and value the real-metal items line by line.

Step one: every piece is photographed in the layout it arrived in, so there is a clean visual record of the contents at the door. Step two: each item is passed under the XRF analyser to identify metal type, gold (and its carat), silver, platinum, palladium, or non-precious base metal. Step three: precious-metal items are sorted into carat groups (9ct, 14ct, 18ct, 22ct gold; sterling silver; platinum) and weighed by group. Step four: the written offer is built showing each group separately with the per-gram rate and the total.

Costume pieces, gold-plated items, silver-plated items and any base-metal jewellery are identified by name on the offer and described, so you can see what was returned versus what was paid for. Stones found inside settings (loose diamonds, sapphires, garnets) are identified and noted; if any are clearly worth more than the gold value they sit in, we say so openly so you can decide whether to remove and sell separately.

Two patterns recur in mixed-box parcels. First, broken or odd-earring pieces routinely carry more total gold weight than the larger statement pieces in the same box, a dozen single earrings can easily weigh more than a single heavy chain. Second, "costume" pieces are sometimes real after all (and "real" pieces are sometimes costume); the XRF settles every question definitively.

Items that often sit in mixed boxes and turn out to be worth meaningful sums: 9ct gold charm bracelets with a dozen charms attached, 18ct signet rings inherited from a grandfather, 22ct chains tucked at the bottom under cotton wadding, gold sovereign or half-sovereign coin mounts, gold watch chains. None of these need to be identified by you before posting, the sorting happens on our side.

Pack the contents in their original box where possible, or transfer to a sturdy small cardboard carton with crumpled paper or bubble wrap to prevent movement. Each individual high-value piece (any large chain, bangle or watch) is worth wrapping individually in tissue inside the larger packing.

Mixed-box parcels span a wide value range, from £150 to £4,000+ depending on contents. If you are unsure whether the total value may exceed £2,500, send us a photograph of the entire box laid out and a rough total weight before posting; we will tell you whether to use the standard cover or arrange a higher cover level.
