About 18k gold
18K gold is 75% pure gold by weight. Pure gold is soft, so jewellers alloy it with harder metals: 18k balances gold content with durability. Its melt value is always a fixed fraction (0.75) of the pure-gold price — derived from spot ÷ 31.1034768 grams per troy ounce.
When buying or selling 18k gold, weigh the item, multiply by the per-gram figure for your currency above, and expect dealer premiums (buying) or margins below melt (selling scrap).
Frequently asked questions
What does 18k gold mean?
18K gold is 75% pure gold by weight — 24 karats is pure gold, so 18k means 18 parts gold out of 24, alloyed with harder metals. The remainder (25%) is typically copper, silver or zinc.
How much is 18k gold worth in US dollars?
18k gold is currently $110.50 per gram ($3,437 per ounce) as of 09:52 UTC.
Why is 18k cheaper than 24k per gram?
Because only 75% of its weight is actual gold. A gram of 18k contains 0.7500 grams of pure gold, so its melt value is that fraction of the pure-gold price.
Is 18k good for jewellery or investment?
18k is a jewellery karat: the alloy makes it harder and more durable, while still holding solid metal value. For pure investment, 24k bullion tracks spot most directly.
