How to Check Gold Purity and BIS Hallmark Before Buying

Buying gold jewellery is an important decision. Whether you are purchasing a ring, chain, earrings, bangles or bridal jewellery, knowing how to identify purity can help you make a more informed purchase.

One of the most important things to look for when buying gold jewellery in India is BIS hallmarking.

What Is Gold Purity?

Gold purity refers to how much pure gold is present in a jewellery alloy.

Common purity levels include:

• 24K – approximately 99.9% pure gold
• 22K – approximately 91.6% pure gold
• 18K – approximately 75% pure gold

Gold jewellery is generally alloyed with other metals to improve strength and durability.

What Is BIS Hallmarking?

The Bureau of Indian Standards (BIS) operates India's hallmarking system for precious metal articles.

A hallmark provides important information about the purity of the precious metal and helps customers make more informed purchases.

What Should You Look For?

When purchasing hallmarked gold jewellery, look for the applicable hallmarking details on the jewellery.

The marking and associated identification information can help establish the declared purity and traceability of the jewellery.

Check the Purity Mark

The purity marking indicates the fineness of the gold.

For example, 22K jewellery may be associated with a fineness of 916, while 18K gold may be associated with 750.

These numbers represent parts per thousand of pure gold.

Ask for the Invoice

A proper invoice is an important part of any jewellery purchase.

Before completing your purchase, check that the bill clearly records relevant product and pricing details. Keep the invoice safely for future reference.

Buy from a Trusted Jeweller

Hallmarking is important, but choosing a reputable jeweller is equally valuable.

A trustworthy jewellery store should provide clear information about:

• Gold purity
• Weight
• Pricing
• Making charges
• Applicable taxes
• Hallmarking
• Product documentation

Don't hesitate to ask questions if any part of the bill or product information is unclear.

Don't Judge Purity by Appearance

The colour or shine of gold jewellery alone cannot reliably tell you its purity.

Two pieces can have different appearances because of their alloy composition, finish or design while having a clearly stated purity level.

Always rely on proper purity markings, documentation and trusted professional information rather than appearance alone.

Understanding hallmarking and gold purity can make your jewellery-buying experience more transparent and comfortable.
