Gold price per gram, live

From troy ounce to price per gram

Gold trades globally in US dollars per troy ounce. To get the price per gram, divide the spot ounce price by 31.1035, then apply the live EUR/USD exchange rate. That's why prices here are shown in both euros and their dollar equivalent.

This calculation applies to pure 24K gold. For any other purity, multiply that per-gram figure by the relevant factor: 22K ×0.916, 18K ×0.75, 14K ×0.585, 9K ×0.375.

Reading the purity table correctly

The 'theoretical value' column is the price of the pure gold content only — it assumes 100% payout, which no buyer actually offers. Use the discounted column, roughly 80% of theoretical value, as a realistic benchmark for a fair gold-buyer offer.

European hallmarks make it easy to identify purity: look for 999 (24K), 916 (22K), 750 (18K), 585 (14K) or 375 (9K) stamped on the piece before you calculate its value.

Frequently asked questions

What is the price of a gram of gold today?

The live price of a gram of pure 24K gold is shown at the top of this page, calculated from the US dollar spot price per ounce and the current EUR/USD rate.

How do you convert from troy ounces to grams?

One troy ounce equals 31.1035 grams. Divide the dollar price per ounce by 31.1035, then convert to euros using the live exchange rate to get the price per gram.

Is the gold price per gram the same everywhere?

The underlying spot price is international and identical everywhere. Only the margin applied by an individual gold buyer or jeweler differs from one shop to the next.

Which price per gram should I use for my jewelry?

Almost never the 24K figure directly: most jewelry is 18K, worth 75% of the pure gold price, or lower purities like 14K or 9K. Use the purity table on this page to find the right multiplier.
