What is 24K gold?
24K gold is pure gold — at least 99.9% fine — and it is the reference grade on which every international spot price is based. It has a deep, warm yellow colour and does not tarnish.
Because pure gold is very soft, 24K is used mainly for investment bars, bullion coins such as the Canadian Maple Leaf and Austrian Philharmonic, and for traditional jewellery in parts of China, India and Southeast Asia where purity is valued above durability.
How the 24K gold price is calculated
Gold is traded internationally as pure 24K metal per troy ounce. To find the 24K price, multiply the spot price by the 24K purity factor of 0.999 and divide by 31.1035 to convert ounces to grams. Today that gives USD 134.51 per gram of 24K gold, compared with USD 134.64 for pure 24K.
Example: a 24K chain weighing 15 g contains 14.98 g of pure gold, so its melt value is USD 2,017.65 (EUR 1,794.12). A 5 g ring is worth about USD 672.55, and 100 g of 24K scrap about USD 13,450.98 before the buyer's margin.
How to recognise 24K gold
Look for the stamps 999, 9999, 24K or 24ct. Investment bars also carry a refiner's mark and serial number. Genuine 24K is noticeably heavy and slightly bendable in thin pieces.
Since the price of 24K is essentially the spot price, the difference between what you pay and the melt value is pure premium. Compare premiums per gram across dealers, and for selling, expect the best percentage of spot for recognised refiner bars.

Compare a 24K 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 24K 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 24K scrap calculator for a net-weight scenario and the purity guide to distinguish stamped fineness from nominal math.
