Calculate the value of gold or silver by weight and purity using live spot prices. Covers common jewelry karats (24k, 18k, 14k, 10k) and silver fineness (fine, sterling, coin), in grams, troy ounces, kilograms, or pennyweight.
About These Prices
Spot prices are pulled live and represent the wholesale market price for pure (999) metal, quoted per troy ounce. Jewelry and coins are rarely pure — a 14k gold ring is about 58.3% gold by weight, so its melt value is the spot price times that purity, not the full spot price. Actual resale or purchase prices from a dealer will typically differ from spot due to premiums, making charges, and dealer margins.
Common Lookups
Selecting Gold + 24k gives you today’s gold price per gram at full purity. Switch purity to 18k for the 18k gold price per gram (75% pure) or 14k for the 14k gold price per gram (58.3% pure) — the two most common jewelry karats in the US. Switch the metal to Silver for the silver price per gram at fine (999), sterling (925), or coin (900) fineness.
Frequently Asked Questions
How is gold price per gram calculated from the spot price?
Spot price is quoted per troy ounce (31.1034768 grams). Divide the spot price by that figure to get the pure-gold price per gram, then multiply by the karat’s purity fraction (for example, 14k is 0.5833) to get the melt value per gram of that karat.
What’s the difference between 14k, 18k, and 24k gold?
The karat number describes purity out of 24 parts. 24k is essentially pure gold (99.9%). 18k is 75% gold mixed with other metals for durability. 14k is 58.3% gold, common in everyday US jewelry because it’s harder and less expensive than higher karats.
Why is my jewelry worth less than the calculator shows?
This tool estimates raw melt value only. Jewelry buyers typically pay a percentage below melt value to cover refining costs and profit margin, and they don’t pay extra for craftsmanship, brand, or gemstones — those factors matter for resale or insurance value, not scrap value.
