🏛️ Indian Hallmarking Guide (Mandatory)

As per Indian law, real gold jewelry must have these 3 specific marks laser-engraved on it:

  • 1
    BIS Logo: A small triangle logo indicating it was verified by the Bureau of Indian Standards.
  • 2
    Purity Grade: A combination of Karat and Fineness (e.g., "22K916" or "18K750").
  • 3
    HUID Code: A 6-digit alphanumeric code (e.g., AB12CD). You can verify this code using the official "BIS Care App" on your phone to see who manufactured it.

🧪 Quick Home Verification Tests

  • 🧲
    The Magnet Test: Pure gold is completely non-magnetic. If a strong magnet attracts your jewelry, it is heavily mixed with iron or nickel (Fake or very low karat).
  • 💧
    The Float Test: Real gold is dense and heavy. If you drop it in a glass of water, it should sink immediately. If it floats or hovers, it's fake.
  • ⚠️
    Acid Test: Jewelers use Nitric Acid. Fake gold turns green, gold over sterling silver turns milky. Only let a professional do this.
