🏛️ 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.

How to Use the Gold Purity & Value Analyzer

The Gold Purity & Value Analyzer is an essential financial utility designed for jewelry buyers, investors, and anyone looking to sell or exchange old ornaments. Instead of relying blindly on a jeweler's verbal estimate, this tool empowers you to calculate the precise intrinsic market value of your precious metals based on their exact weight and karat purity, ensuring you get a fair deal every time.

Understanding Karats and Indian Hallmarking

Not all gold jewelry is created equal. Pure 24K gold is too soft for daily wear, so it is alloyed with other metals to create durable 22K, 18K, or 14K pieces. Alongside the value calculator, this tool includes a mandatory Indian Hallmarking Guide and quick home verification tests to help you check stamps and authenticity. Look for these key markers on your jewelry:

  • The BIS Logo: The official mark of the Bureau of Indian Standards confirming the item has been verified at an official assaying center.
  • Purity Grade: A number indicating the karat and fineness (e.g., "22K916" means 22 Karat gold with 91.6% purity).
  • Six-Digit HUID: A unique alphanumeric code that allows you to verify the jewelry's exact origin and authenticity.

Step-by-Step Guide to Calculating Gold Value

  1. Enter Current Market Rate: Input today's standard market price for 10 grams or 1 gram of pure gold.
  2. Select Karat Purity: Choose the purity level of your specific item (such as 24K, 22K, 18K, or 14K) to automatically adjust the calculation formula.
  3. Input the Weight: Enter the exact physical weight of your jewelry in grams.
  4. Review the True Value: The tool instantly calculates the intrinsic raw metal value of your item before making any buying or selling decisions.

Frequently Asked Questions (FAQ)

Q: Does the calculated value include making charges or taxes?
A: No. This calculator determines the raw intrinsic value of the pure gold itself. Jewelers will typically add separate making charges (labor costs) and mandatory taxes (such as GST in India) on top of this base metal value.

Q: Can I use this calculator offline at the jewelry showroom?
A: Yes! Because Hapsas operates as an offline-first Progressive Web App (PWA), you can calculate live values right at the jeweler's counter, even if you do not have mobile data or Wi-Fi access.

Q: Is this an official certified valuation?
A: No. This fast, free utility is provided strictly for educational and informational purposes to help you understand market estimates. For an official legal valuation, always visit a certified jeweler or authorized assaying center.
