The value of gold jewellery is determined almost entirely by two things: weight and purity. Unlike antiques or designer pieces, the brand name on a gold ring rarely adds meaningful value — the market cares about how many grams of pure gold the piece contains.
This is good news for sellers. A plain 18ct gold ring is worth exactly the same as an ornate 18ct gold ring of the same weight. Condition matters very little — broken clasps, bent settings and scratched surfaces don't change the underlying gold content.
Carats explained
In the UK, gold purity is expressed in carats — a measure of the proportion of pure gold in the alloy. 24 carat is pure gold; lower carats contain a mix of gold and other metals such as copper, silver or palladium.
