How to use the 18ct gold price in the UK
The 18ct gold price UK page is built for a practical selling question: what is a piece marked 750 worth in pounds today? The calculator starts with the live 24ct gold price per gram in GBP, applies the 18ct purity factor of 75.0%, and then shows the result by gram, troy ounce, kilogram and common selling units.
18ct gold is a familiar UK fine-jewellery standard, so buyer quotes should be compared against the 750 melt value rather than the 24ct spot price. That local context matters because a US dollar 14K page or a generic global spot chart does not answer the same question as a UK seller typing 18ct gold price per gram UK, 750 gold value, or scrap gold price UK. UK users normally need a GBP figure they can compare against a high-street jeweller, a postal gold buyer, a Hatton Garden-style dealer or a local cash-for-gold quote.
Price per gram versus buyer offer
The number on this page is a melt-value benchmark, not a guaranteed payout. A buyer has to test the item, check the hallmark, remove stones or non-gold parts, cover refining costs and allow for business margin. That is why the best way to compare offers is to ask what percentage of melt value is being paid, not just whether the cash number sounds high.
For example, if you have 8 grams of 18ct gold, the current melt value is roughly £656.46. If a buyer offers less, the gap may be reasonable if the item has stones, uncertain purity or a small lot size. If the buyer will not show weight, purity, spot price and payout percentage, compare the offer with another buyer before accepting it.
Hallmark and purity checks
UK gold jewellery is commonly checked by hallmark or fineness stamp. A 750 mark points to 18ct gold, but hallmarks can be worn, incomplete or misread. If the item is valuable and the stamp is unclear, use a proper test from a reputable jeweller or buyer before relying on the calculator. Do not value plated, rolled gold or gold-filled items as solid 18ct gold.
The safest workflow is simple: identify the hallmark, weigh only the gold portion, use the matching 18ct row, and then compare the payout percentage. If the piece is signed designer jewellery, antique, a collectible coin or set with valuable stones, melt value may be only a floor rather than the best selling price.

Confirm the buyer is valuing the piece as 750 / 18ct, not averaging it with another purity.
Check net gold weight
Remove or account for stones, steel, springs, watch parts and non-gold clasps before comparing quotes.
Compare payout rate
Ask what percentage of melt value is being paid so local, postal and refiner offers can be compared fairly.
