In Europe and North America, 18K (hallmarked “750”) is the standard for fine and designer jewelry. Its 25% alloy makes it hard enough to set diamonds securely and resist daily wear, while still being unmistakably gold and comfortable for most wearers.
The alloy decides the colour: copper gives rose gold, while palladium or rhodium-plated nickel give white gold. All three are still 75% pure, so they share the same metal value shown here — the difference is purely in the alloy blend and finish, not the gold content.
18 karat gold is 75% pure (hallmarked “750”), with 25% other metals that add strength and enable colours like white and rose gold.
It is hard-wearing and holds gemstones securely while still being clearly precious, which is why it dominates Western fine jewelry.
Multiply the 24K spot price by 0.75, since 18K gold is 75% pure.
