🔍 1. Look for the BIS Logo
- The hallmark is stamped on the inner side of bangles, rings, chains, or pendants.
- The BIS (Bureau of Indian Standards) triangular logo ensures government-certified purity.
🔢 2. Check the Purity Mark
- The purity is written in karat (K) or fineness number:
- 22K → 916 (91.6% pure gold)
- 18K → 750 (75% pure gold)
- 14K → 585 (58.5% pure gold)
- 24K → 999 (99.9% pure gold, usually coins/bars)
🏷 3. Look for Jeweler’s Identification & Assay Centre Mark
- Every BIS-hallmarked item has a 6-digit alphanumeric code (HUID).
- This code is unique to your piece of jewelry.
📱 4. Verify with BIS CARE App
- Download the BIS CARE app (available on Play Store & App Store).
- Enter the HUID code from your jewelry.
- The app shows purity, jeweler details, and hallmark authenticity.
