Three marks to look for
HUID-based gold hallmarks have three components. Check the marks on your jewellery alongside its stated gold purity.
Gold purity
The purity mark states the caratage and fineness of the gold, such as 14K585 or 18K750.
Unique HUID
A six-character alphanumeric Hallmark Unique Identification code identifies the individual hallmarked article.
Our business registration number is separate from an item’s HUID. Gold hallmarking concerns the precious metal’s purity; diamond grading reports describe the diamond separately.
How to verify your HUID
- Find the six-character HUID marked on your gold jewellery.
- Open the official BIS CARE app and select Verify HUID.
- Enter the code and compare the returned details with your jewellery. Contact us if you need help locating the mark or understanding the result.
