Three marks tell the story
For HUID-based hallmarked gold jewellery, look for these three identifiers on the article.
Purity and fineness
Shows the karat grade and gold content in parts per thousand.
Six-digit HUID
A unique alphanumeric identifier that can be checked in the BIS Care app.
Purity at a glance
Karat and fineness, decoded
Karat describes the proportion of gold in an alloy. Fineness expresses that proportion in parts per thousand. The stamped grade helps you recognise what an article claims; professional testing confirms its actual purity.

Before you sell
A five-minute preparation checklist
A little preparation makes the valuation easier to follow and gives you a cleaner record of the offer.

Check visible hallmark details and verify the HUID in the official BIS Care app.
- 4
Ask for the tested purity, net gold weight, applied rate and deductions in writing.
- 5
Review the final offer at your own pace before deciding whether to sell.
Official consumer resources
Verify independently when you need to
BIS states that consumers can sell old hallmarked or unhallmarked jewellery, request testing from a BIS-recognised Assaying and Hallmarking Centre, and verify a hallmarked item's HUID through the BIS Care app.
