What is the BIS Hallmark?

BIS stands for Bureau of Indian Standards — India's national standards body, functioning under the Government of India. A BIS Hallmark on gold jewellery is a legal guarantee of purity, issued after the piece is tested at a BIS-licensed Assaying and Hallmarking Centre. Since June 2021, BIS Hallmarking has been mandatory for all gold jewellery sold in India — meaning any shop selling gold without a BIS Hallmark is operating illegally.

What is 22K (916) Gold?

22 Karat gold (916 purity) contains 91.6% pure gold with a small amount of other metals (silver or copper) to give it the hardness needed for jewellery. All traditional Maharashtrian bridal ornaments like Mangalsutras, Kolhapuri Saaj, gold chains, and kadas are crafted in 22K gold. Every piece at Surajmal Fulchand Jewellers is 22 Karat (916 purity) BIS Hallmarked.

What is 24K (999) Gold?

24 Karat gold (999 purity) is 99.9% pure but is too soft to be crafted into durable, wearable jewellery. It bends, scratches, and loses its shape easily in daily wear. It is typically used for gold coins, bars, and bullion investments rather than everyday ornaments.

What is a HUID Number and How Do You Verify It?

HUID stands for Hallmark Unique Identification — a 6-digit alphanumeric code stamped on every BIS Hallmarked gold piece in India, mandated by the Government of India since June 2021. Each HUID is unique to a single piece of jewellery and records its purity, weight, and the hallmarking centre that certified it. No two pieces share a HUID.

Step-by-Step Guide to Verifying Your HUID:

  1. Download the BIS Care mobile app (available on Android and iOS — search "BIS Care" on the Play Store or App Store).
  2. Open the app and tap on the "Verify HUID" section.
  3. Enter the 6-digit alphanumeric HUID number stamped on your jewellery piece (e.g., A1B2C3).
  4. The app will display the full details of your jewellery — including the purity grade, weight, and the name of the licensed hallmarking centre confirmed by the Bureau of Indian Standards.

Every piece at Surajmal Fulchand Jewellers, Gujari Bazar, Kolhapur carries a verifiable HUID number — your permanent proof of the gold's purity, backed by the Government of India's Bureau of Indian Standards.
