Understanding Gold Purity
Gold purity is measured in karats (K). 24K is 99.9% pure gold, ideal for investment bars and coins. 22K (91.67% pure) is the standard for Indian jewelry as pure gold is too soft for daily wear. 18K (75% pure) is used in diamond-studded and designer jewelry. Always check the BIS hallmark — mandatory since June 2021 — which certifies purity.
