18K Gold Price Today per Gram & Ounce
18K gold contains 75.0% pure gold — 750 parts of gold per 1,000 — with the remainder made up of alloy metals like copper, silver and zinc that give it strength and colour. That purity is what sets its price relative to pure 24k gold.
To price it, we take the live international spot price of $4,113.70 per troy ounce, divide by 31.103 to get the per-gram 24k value, then scale by 18K's purity. The table below applies that to every common weight, from a single gram to a full kilogram, so you can value jewellery, coins or scrap at today's rate.
