What is 9K gold?
9K gold is 37.5% gold and is the lowest karat legally hallmarked as gold in the United Kingdom, Ireland and Australia. It is commonly called 375 gold.
9K is popular in the UK for affordable rings, lockets and chains. Its high alloy content makes it hard-wearing, though it can look paler than higher karats.
How the 9K gold price is calculated
Gold is traded internationally as pure 24K metal per troy ounce. To find the 9K price, multiply the spot price by the 9K purity factor of 0.375 and divide by 31.1035 to convert ounces to grams. Today that gives USD 50.02 per gram of 9K gold, compared with USD 133.38 for pure 24K.
Example: a 9K chain weighing 15 g contains 5.63 g of pure gold, so its melt value is USD 750.27 (EUR 669.18). A 5 g ring is worth about USD 250.09, and 100 g of 9K scrap about USD 5,001.81 before the buyer's margin.
How to recognise 9K gold
Look for 375 or 9ct. UK pieces also carry an assay office mark (such as an anchor for Birmingham or a leopard's head for London).
Many UK cash-for-gold shops quote per-gram prices for 9ct. Compare those quotes with the melt value here; request written net offers and compare each percentage without assuming a universal payout. Live quotes are cached for five minutes; open pages request updates about every minute. Check the quote timestamp; see our methodology for details.
Compare a 9K buyer quote with the metal value
Weigh only the gold-bearing alloy. Stones, steel springs and watch movements do not contribute the same gold fraction. A tested fineness may differ from the nominal karat fraction or the common hallmark, especially for repaired or mixed constructions. Request accepted grams, tested grade and all deductions in writing. Divide a net cash offer by the matching melt reference to compare its percentage; a high advertised rate is not helpful when another fee is deducted afterward.
Do not assume every 9K piece is best sold for scrap. A maker, design, gemstone or collector market can create resale value beyond the gold. Preserve that possibility before destructive testing. A pawn loan has separate borrowing charges and redemption terms; its advance is not a cash-sale appraisal. Local tax rules depend on the transaction and product. Use the 9K scrap calculator for a net-weight scenario and the purity guide to distinguish stamped fineness from nominal math.
