18k Gold Price Per Gram
18k gold is worth $103.44 a gram today — 75.00% gold at $4,289.80 spot. That is $160.87 a pennyweight and $3,217.35 a troy ounce, before any buyer's cut.
18k is 75% gold, stamped 750, and the usual karat for fine jewellery and watch cases in Europe. It carries 29% more gold per gram than 14k, which is the whole of the price difference between them at melt.
The number above is melt value: the gold actually inside a gram of this karat, priced at the live spot price. It is not what anyone will pay you. Every buyer offers a fraction of melt, so the table further down turns a quoted percentage into dollars per gram — the conversion a buyer-run price page leaves for you to do.

A buyer's offer, in dollars per gram
Offers are quoted as a percentage of melt, or as a flat price you can turn back into one. This is the same 18k gram at each level, so two quotes can be compared as numbers.
| Offer (% of melt) | Per gram | Per dwt | Buyer keeps per gram |
|---|---|---|---|
| 50% | $51.72 | $80.43 | $51.72 |
| 60% | $62.06 | $96.52 | $41.38 |
| 70% | $72.41 | $112.61 | $31.03 |
| 80% | $82.75 | $128.69 | $20.69 |
| 90% | $93.10 | $144.78 | $10.34 |
These steps are for comparison, not a claim about what any buyer pays. A buyer who will not state an offer as a percentage of melt has told you something about the offer.
If it is being sold, the proceeds are a second decision
Jewellery is the most expensive way to own gold: the design and labour you paid for are not bought back, which is why melt is a fraction of the ticket price. If what you wanted was exposure to gold rather than the object, the next question is which form that should take — and it is not automatically another physical piece.
FAQ
Frequently asked questions
How much is 1 gram of 18k gold worth today?
$103.44 in melt value at the current spot price of $4,289.80 a troy ounce. A gram of 18k holds 0.7500 grams of pure gold, and pure gold is $137.92 a gram. Multiply your piece's weight in grams by $103.44 and you have its melt value.
How much is 18k gold worth per ounce?
$3,217.35 per troy ounce, the unit gold is priced in. If you weighed the piece on a kitchen scale, that reads in avoirdupois ounces, which are about 9% lighter: one kitchen-scale ounce of 18k is worth $2,932.48. Mixing the two up is the most common error in pricing gold at home.
How much will a buyer pay for 18k gold?
Some fraction of melt — how much depends on the buyer and on how much you bring, and it varies more between buyers than most sellers expect. At 70% of melt, 18k fetches $72.41 a gram; at 90%, $93.10. Ask every buyer for their offer as a percentage of melt, and use the table on this page to compare them in dollars.
Is 18k gold worth more than 14k?
Per gram, yes, by exactly the ratio of gold content: 75% against 58.33%, so 18k melts at $103.44 a gram against $80.45 for 14k at today's spot. Whether a finished piece is worth more depends on its weight, and 18k pieces are often lighter for the same design.
How can I tell if a piece is solid 18k gold?
Look for the karat stamp (18K or 750). Then look for what follows it: GF, GP, HGE, RGP or a fraction like 1/20 mean gold-filled or gold-plated — a thin layer over base metal, worth a small fraction of the solid price. A buyer will test the piece rather than trust the stamp, and that test is what the offer is based on.
