Gold jewellery in India is sold in 22k, 18k, and 14k — and the only way to know which one you're actually getting is the BIS hallmark, not the seller's word for it.
What the hallmark actually shows
A genuine BIS hallmark carries four marks: the BIS logo, the purity grade (916 for 22k, 750 for 18k, 585 for 14k), the hallmarking centre's mark, and a unique HUID (Hallmark Unique Identification) number. That HUID is searchable on the BIS Care app — if a piece doesn't have one, or the number doesn't resolve, walk away.
Why the karat number matters more than it looks
Higher karat isn't automatically "better" — it's a trade-off. 22k is closer to pure gold and holds resale value best, but it's soft and scratches easily, which is why it's rarely used for rings you wear daily. 18k mixes in more alloy for durability, making it the standard for rings and everyday pieces. 14k is even sturdier and lower cost, common in Western-style fine jewellery.
Three questions to ask before you pay
- Can I see the HUID? It should be lasered onto the piece, not just printed on the invoice.
- Is the price broken down? Gold rate (by weight) and making charges should be itemised separately — if a seller only gives you one number, ask why.
- Is there a buy-back or exchange policy? Reputable sellers will take the piece back at the prevailing gold rate, minus a small deduction. If there's no such policy at all, that's a signal.
None of this is complicated once you know to look for it — it just isn't something most buyers are told to ask.
