Jewelry Hallmark Guide: How to Read Gold & Silver Marks in India

If you’ve ever seen a tiny number or symbol on a ring and wondered what it means, you’re not alone. Hallmarks are the country’s way of telling you what metal you’re holding and whether it meets quality standards. Knowing these marks can save you from buying cheap knock‑offs and help you pick pieces that truly shine.

Understanding Gold Hallmarks

Gold hallmarks usually show purity. In India you’ll see numbers like 916, 875, 750, or 22K. 916 means 91.6% pure gold (22 karat), while 875 is 87.5% (21 karat). The BIS (Bureau of Indian Standards) stamp is a small triangle‑shaped figure with a four‑digit number – that’s the hallmark office code. If you spot a 916 and a BIS triangle together, you’re looking at solid gold that’s been tested for quality.

Quick test: hold the piece under light and check the numbers. If they’re faint or missing, ask the seller for a BIS certificate. A genuine certificate matches the hallmarks on the item, so you can verify it before paying.

Spotting Silver Marks & Common Stamps

Silver uses a different set of numbers. The most common marks are 925 (sterling silver) and 833 (Indian standard silver). Just like gold, the BIS stamp appears alongside the purity number. If you see 925 and a triangle, that’s safe silver. 833 is older but still legitimate – it means 83.3% pure silver.

Another thing to watch for is the “silver plating” sign. A thin layer of silver on a base metal often carries no hallmarks or just a small “silver‑plated” tag. Use a magnet: if the piece sticks, it’s likely not solid silver. Real silver won’t be magnetic.

Now that you know the basics, here are three practical steps to double‑check any jewelry:

1. Look for the purity number (e.g., 916, 875, 925, 833).
2. Find the BIS triangle and note the four‑digit office code.
3. Ask for the BIS certificate and match the code to the piece.

Following these steps in a shop or online can prevent a costly mistake. If a seller can’t produce a certificate or the hallmarks look worn out, walk away – it’s not worth the risk.

Hallmarks also tell you about the metal’s value. Gold at 916 purity commands a higher price than 750, and silver at 925 is more valuable than 833. Knowing this helps you compare prices and negotiate better deals.

In everyday life, you’ll see hallmarks on everything from wedding bands to bangles. Treat each mark as a quick health‑check for the piece. The more you practice reading them, the easier it gets.

Remember, the hallmark system exists to protect you. It’s a simple code that, once cracked, makes buying jewelry a lot less stressful. Keep this guide handy, and the next time you shop, you’ll spot genuine gold and silver in seconds.
