Gold purity by karat
The karat stamp tells you how much pure gold your item contains. Higher purity means a higher value per gram.

|---|---|---|
| 24K | 99.9% | Purest gold, softest |
| 21K | 87.5% | Popular in the Middle East |

Frequently asked questions
How do I calculate the value of my gold jewelry?
Determine your gold's karat (purity), weigh it in grams or troy ounces, and check the current gold spot price. The metal value equals weight multiplied by the purity percentage and the gold price per gram. Our calculator does this automatically using real-time prices.
What is the difference between 14K, 18K, 21K and 24K gold?
Gold purity is measured in karats out of 24. 24K is 99.9% pure, 21K is 87.5% pure, 18K is 75% pure, and 14K is 58.3% pure. Higher karat means more pure gold content and a higher value per gram.
How many grams are in a troy ounce of gold?
One troy ounce equals 31.1035 grams. Gold spot prices are quoted per troy ounce, so the calculator converts your weight automatically whether you enter grams or troy ounces.
How accurate is this gold calculator?
It uses real-time gold spot prices and the standard industry valuation formula, so the metal value estimate is highly accurate. Actual offers vary based on dealer margins, craftsmanship, and market conditions.
Should I accept a jeweler's offer below market value?
Offers 10-20% below melt value are common because dealers have refining costs and profit margins. The calculator flags whether an offer is good, fair, or poor so you can negotiate with confidence.
