Understanding BIS Hallmark Jewellery: How to Read It, Verify It, and Why It Matters

Understanding BIS Hallmark Jewellery: How to Read It, Verify It, and Why It Matters

Short answer

  • A hallmark is an independent purity certification stamped on your jewellery.

  • In India, BIS hallmarking (with HUID) is the gold standard.

  • At Archana Aggarwal Timeless Jewellery, every gold piece is 100% BIS-hallmarked and traceable.

What is BIS hallmark jewellery?

A BIS hallmark is a set of marks applied by an authorised assaying centre that confirms the exact purity (caratage) of your gold. It protects you from under-karating and misrepresentation—turning “claimed purity” into “verified purity.”

The modern Indian hallmark (what you’ll see on your piece)

  • BIS logo: Confirms certification by the Bureau of Indian Standards.

  • Caratage/purity mark: e.g., 22K (91.6%), 18K (75.0%).

  • Jeweller’s ID and Assaying Centre mark: Who made it and who tested it.

  • HUID (Hallmark Unique Identification): A unique alphanumeric code that ties your exact piece to BIS records.

How to check a hallmark on gold jewellery

  • Find the mark: Inside the ring shank, on the clasp, or the underside of pendants/earrings.

  • Read the purity: 22K or 18K should be clearly stamped.

  • Confirm the HUID: Use the BIS Care app or official BIS channels to verify the HUID matches the item you’re holding.

  • Cross-check the seller: Ensure the jeweller is BIS-registered.

Why it matters

  • Accurate value: Purity drives price. A certified 22K piece retains value better than a “claimed 22K” that tests lower.

  • Resale/trade-in confidence: Buyers and resellers trust hallmarked gold; non-hallmarked pieces face friction and discounts.

  • Protection from common scams: Under-karating, mislabelled alloys, and non-compliant hallmark stamps are filtered out by BIS controls and HUID traceability.

Archana Aggarwal’s stance on hallmarking (our brand promise)

  • 100% BIS hallmarking with HUID for all gold jewellery.

  • Transparent purity disclosure on product pages and in-store.

  • Heritage-level craftsmanship—polki, modern vintage, and contemporary collections—built on verified materials.

  • Post-purchase support: We stand behind purity and craftsmanship for the lifetime of the piece.

How to identify authentic 22K vs 18K at a glance

  • Colour tone: 22K appears richer, warmer; 18K is subtly cooler due to alloy mix.

  • Wear intent: 22K suits heirloom and traditional pieces; 18K excels for contemporary designs needing strength.

  • Hallmark match: The purity stamp must align with the design’s intent and your invoice.

FAQs 

Is BIS hallmarking mandatory?

In India, BIS hallmarking has been widely enforced; always prefer hallmarked gold for purchases.

What is HUID, and why should I care?

It’s your piece’s unique ID, enabling easy authenticity checks and traceability.

Can gemstones and settings affect the hallmark?

Hallmarking certifies gold purity; gemstones are assessed separately.

Does hallmarking add cost?

Minimal, compared to the assurance it provides. The absence of hallmarking can be far costlier at resale.

How do I verify a hallmark before buying online?

Check the product listing for BIS and HUID details, confirm with the brand, and verify on BIS channels.
