Gold Hallmark: How to Check the Purity of Your Gold Jewellery

A gold hallmark is an official mark that certifies the purity of gold jewellery. It helps buyers verify the gold content and make informed purchasing decisions.

What Does a Gold Hallmark Indicate?

A hallmark typically identifies the gold`s purity, the jeweller or manufacturer, and the relevant testing or certification details. In India, BIS hallmarking helps consumers check whether their jewellery meets the declared purity standards.

Common gold purity marks include:

- 24K / 999: Approximately 99.9% pure gold

- 22K / 916: 91.6% gold, commonly used for Indian jewellery

- 18K / 750: 75% gold

- 14K / 585: 58.5% gold

- 9K / 375: 37.5% gold

Where Can You Find the Hallmark?

The hallmark is usually stamped on a less visible part of the jewellery, such as the inside of a ring, a chain clasp or the back of a pendant. Buyers should inspect these marks before purchasing gold ornaments.

Why Is Hallmarking Important?

Gold hallmarking helps buyers confirm the declared purity, assess resale or exchange value, and reduce the risk of purchasing lower-purity gold sold as higher-purity jewellery.

Pure 24K gold is relatively soft, so jewellers generally mix it with other metals to make durable ornaments. The purity mark indicates the proportion of gold in the jewellery.

Tips for Buying Hallmarked Gold

Before buying gold jewellery, check the BIS hallmark and applicable purity details. Verify the hallmark using the official BIS verification system, where applicable, and request an invoice showing the jewellery`s weight, purity, making charges and GST.

In short, a gold hallmark is an important indicator of jewellery purity. Checking it before purchase helps consumers make informed decisions and buy gold with greater confidence.
