What is 20K gold?
20K gold contains 83.3% pure gold, with the remainder made of alloy metals such as copper, silver and zinc that add hardness and change the colour.
20K is less common than 14K, 18K or 22K, but it appears in some regional jewellery traditions and in vintage pieces.
How the 20K gold price is calculated
Gold is traded internationally as pure 24K metal per troy ounce. To find the 20K price, multiply the spot price by the 20K purity factor of 0.8333 and divide by 31.1035 to convert ounces to grams. Today that gives USD 112.20 per gram of 20K gold, compared with USD 134.64 for pure 24K.
Example: a 20K chain weighing 15 g contains 12.50 g of pure gold, so its melt value is USD 1,682.99 (EUR 1,496.53). A 5 g ring is worth about USD 561.00, and 100 g of 20K scrap about USD 11,219.92 before the buyer's margin.
How to recognise 20K gold
Look for a 20K or 833 stamp on the inside of a ring band, on the clasp of a chain or on the back of a pendant.
Compare several buyers' offers as a percentage of the melt value shown on this page before you sell. 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 20K 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 20K 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 20K scrap calculator for a net-weight scenario and the purity guide to distinguish stamped fineness from nominal math.
