What 9K gold is worth
9K gold is approximately 37.50% pure. Its melt value is weight in grams × 9/24 ÷ 31.1035 × the live gold price per troy ounce. The calculator applies that formula before showing buyer discounts.
Where 9K gold appears
9K, 9ct, and 375 describe the same 37.5% gold basis. The remaining 62.5% is alloy metal; color does not change the melt factor when the fineness and net metal weight are the same.
A 375 stamp versus a complete UK hallmark
A complete UK hallmark gives more evidence than a standalone 375 stamp. Government hallmarking guidance identifies the sponsor or maker, the fineness, and the assay office; the date letter is optional.
Why a small 9ct item may have no hallmark
UK guidance exempts gold articles below 1 gram from compulsory hallmarking. An exempt light item is not automatically fake, but its karat still needs reliable testing before you price it as 9ct gold.
Melt value is the negotiating yardstick
Jewelry buyers pay below melt to cover testing, refining, shipping, and margin. Compare every dollar quote with the melt value and get at least three offers before selling.
Frequently asked questions
How much is 9K gold worth per gram?
The live melt value per gram is gold spot ÷ 31.1035 × 9/24. The calculator updates that amount when the live feed loads.
What percentage of pure gold is 9K?
9K gold is approximately 37.50% pure gold; the balance is alloy metal.
What marks identify 9K gold?
Common marks include 9K, 9KT, 9ct, or 375. A mark is a starting point rather than proof, so uncertain or valuable pieces should be tested without damaging them.
Will a buyer pay the full melt value?
Usually not. Scrap-jewelry buyers deduct their costs and margin, so compare offers as a percentage of melt.
Is 9ct the same as 9K gold?
Yes. Both mean nine parts gold out of 24, or 37.5% gold, commonly expressed as a 375 fineness mark.
Does a 375 stamp prove a UK hallmark?
No. A full UK hallmark also includes a sponsor or maker mark and an assay-office mark. Treat 375 alone as a stated fineness until the item is verified.
