Scrap value comes from the pure gold only. This chart shows the stamp, purity, and how much actual gold sits in 10 grams of each karat.
| Karat | Stamp | Gold content | Pure gold in 10 g |
|---|---|---|---|
| 24K | 999 | 99.9% | 9.99 g |
| 22K | 916 | 91.7% | 9.17 g |
| 18K | 750 | 75.0% | 7.50 g |
| 14K | 585 | 58.5% | 5.85 g |
| 10K | 417 | 41.7% | 4.17 g |
| 9K | 375 | 37.5% | 3.75 g |
Melt value = pure gold weight × current spot price per gram. Dealers typically pay 70-90% of melt.
Gold karat measures purity. 24K is pure gold (99.9%). 18K is 75% gold. 14K is 58.5% gold. 10K is 41.7% gold. The remaining percentage is alloy metals (copper, silver, zinc) that add strength but do not carry gold value. Higher karat = more pure gold = higher melt value per gram.
