The Bureau of Indian Standards (BIS) hallmark is the government benchmark of precious metal purity across India. Every hallmarked ornament carries three mandatory laser engravings: the triangular BIS logo, the purity grade number, and a unique 6-digit alphanumeric HUID (Hallmark Unique Identification) code.
Decoding Karat Grades & Numeric Hallmarks
- 24K Gold (999 Hallmark): 99.9% pure bullion. Because 24K is too soft for intricate jewelry, it is primarily purchased as minted bars, investment coins, or bullion biscuits.
- 22K Gold (916 Hallmark): 91.6% pure gold alloyed with 8.4% copper and silver for durability. This is the standard grade for traditional Indian bridal jewelry, chains, and bangles.
- 18K Gold (750 Hallmark): 75.0% pure gold alloyed with 25% other metals. Widely used for diamond-studded rings, earrings, and contemporary lightweight daily wear.
- 14K Gold (585 Hallmark): 58.5% pure gold, popular for affordable modern designer jewelry.
