The identifier karat is used on all jewelry made of genuine gold, and all jewelry produced of real gold will have a karat stamp. The commonly used karats are:
– 10k or 417- 41.7% of pure gold
– 14k or 585 – 58.5% of pure gold
– 18k or 750 – 75% of pure gold
– 24k or 999 – 100% of pure gold
These karats apply to any color of gold, thus 14k yellow and 14k rose gold will both contain the same proportion of gold (58.5%).
