What do BIS hallmark numbers mean?
In India, gold jewellery is hallmarked by the Bureau of Indian Standards (BIS). The hallmark number tells you how much pure gold is present per 1,000 parts — so 916 means 916 grams of pure gold per kilogram, or 91.6% purity.
24K (999) — Pure gold (99.9%). Used for investment bars, coins, and digital gold.
22K (916) — 91.6% pure. The most popular purity for jewellery in Kerala. Durable and bright.
18K (750) — 75% pure. Preferred for diamond-studded and lightweight daily-wear pieces.
14K (585) — 58.5% pure. Common in western-style rings and pendants. More affordable.
9K (375) — 37.5% pure. Entry-level gold, used in budget jewellery segments.
When you buy jewellery, ask for a BIS hallmarked piece. The hallmark guarantees the purity is independently certified — this protects you from impure gold and makes resale easier. Since August 2021, BIS hallmarking is mandatory for all gold jewellery sold in India.
The calculator above uses today's official Kerala board rate for 24K gold as the base and derives all other karats proportionally. This gives you the raw gold value. Add making charges (typically 8–25%) and 3% GST to estimate the full showroom price.
