Understanding Gold Karats
Gold purity is measured in karats (K). Pure gold is 24K. Lower karat values indicate gold alloyed with other metals for durability:
- 24K — 99.9% pure, softest and most valuable per gram
- 22K — 91.7% pure, popular for fine jewelry and coins
- 18K — 75.0% pure, widely used in fine and luxury jewelry
- 14K — 58.3% pure, a popular choice for everyday jewelry in the U.S.
- 10K — 41.7% pure, a durable, lower-gold option commonly sold in the U.S.
