How much is a gram of gold worth?

The 10-second calculation

Grams × price per gram for your purity = theoretical value, shown live in euros and US dollars on this page. Then subtract the buyer's margin, typically 10-30%, to estimate what you'll actually be offered.

European hallmarks tell you which multiplier to use: 999 for pure gold, 916 for 22K, 750 for 18K, 585 for 14K and 375 for 9K. Check the stamp on your piece before doing the math.

Why weight matters more than you think

A simple ring typically weighs 2-4 g, a chain 3-8 g, a bracelet 8-15 g — guessing by eye is usually wrong by 30% or more. Always weigh jewelry on a digital scale, excluding stones, pearls and clasps that aren't gold.

On a single gram the difference between offers looks small, but across 20-30 grams of jewelry it can add up to real money, so it's worth comparing several buyers before selling.
