Calculate your gold above, then enter the net amount a buyer would pay after fees. We compare it with the full melt value, before the payout percentage you selected.
Enter a valid weight and price above to compare an offer.
A percentage alone does not establish a fair price. Compare tested purity, net weight, fees and competing written quotes. Brand, stones and collectible value can justify a price above melt.

Britain writes “carat”, abbreviated ct. Karat with a K is the American spelling for the same measure.
9ct (375) is the lowest recognised UK gold hallmarking fineness. This is separate from US marketing guidance; the FTC removed its former 10K threshold in 2018.
Compulsory on gold articles over 1 gram, under the Hallmarking Act 1973.
To put this into practice, use Gold Price Per Gram, check the assumptions with Scrap Gold Calculator, and compare the result in 9K Gold Price & Calculator.
9ct gold is 375 parts per thousand, or 37.5% gold, and it is the mainstay of the UK high street in a way it simply is not in the United States. Because 9ct is only just over a third gold, its melt value per gram is roughly 40% of a 24ct gram, which surprises people selling inherited pieces.
The practical consequence is that a heavy 9ct chain can be worth less than a light 18ct one. Always calculate fine gold weight - grams multiplied by the fineness - rather than comparing gross weights.
A full UK hallmark is a record, not just a purity mark. It carries the sponsor or maker mark, the millesimal fineness in a shaped shield, the assay office town mark, and often a date letter that identifies the exact year of assay.
Four assay offices remain: London (leopard head), Birmingham (anchor), Sheffield (rose) and Edinburgh (castle). Because the system is compulsory and centrally recorded, British pieces are among the easiest in the world to date and attribute, which occasionally matters far more than the metal value.
Investment gold - bullion bars and coins meeting the statutory fineness and form tests - is exempt from VAT in the UK. That is why a sovereign or a Britannia is quoted close to its metal value rather than with tax on top.
Jewellery is not investment gold, so VAT applies when you buy it new. It does not apply to you when you sell scrap to a dealer as a private individual: you are selling an asset, not making a taxable supply. Treat any offer that mentions deducting VAT from your scrap payment with suspicion.
The same spread applies as anywhere: specialist refiners and mail-in buyers sit at the top, high-street jewellers in the middle, and pawnbrokers lowest. Ask for the offer in pounds for your specific weight, the spot price used, and the fineness assigned to each group.
Because 9ct is so common in the UK, sorting matters more than usual. A mixed British lot weighed as one pile will often be priced near 375, and a 750 piece hidden in it is then worth exactly half what it should be.
We use primary or official references for measurement, purity, hallmark, and coin specifications. Market prices remain time-sensitive and are timestamped separately.
9ct is 375 fine, so a gram contains 0.375 grams of pure gold. Multiply the pure-gram price by 0.375. At a spot price of £3,200 per troy ounce that is roughly £38.60 per gram of 9ct before any buyer deduction.
Yes, for gold purity. Britain writes carat and abbreviates it ct; the United States writes karat and abbreviates it K. Confusingly, carat also measures gemstone weight, which is unrelated - a 1 carat diamond in an 18ct ring uses the word twice with two different meanings.
Gold articles over 1 gram sold in the UK must be hallmarked under the Hallmarking Act 1973. Older, lighter or imported pieces may lack one, which does not make them fake - it just means you should test rather than assume.
Not as a private individual selling your own property. VAT applies to buying new jewellery. Investment gold - qualifying bullion bars and coins - is VAT exempt in both directions.
