What does 916 mean on gold jewellery?
The number 916 is one of the most commonly seen markings on gold jewellery in India. It signifies that the jewellery contains 91.6 per cent pure gold, which is equal to 22-karat gold.
The remaining 8.4 per cent is made up of other metals such as copper, silver, or zinc. These metals are added to improve durability and make the jewellery suitable for everyday wear. Most traditional Indian gold jewellery is made using 22-karat gold.

Because of its hardness, 18-karat gold is widely used in jewellery studded with diamonds and gemstones. It is also popular in modern and designer jewellery collections.

Why 999 gold is considered the purest
The number 999 represents 99.9 per cent pure gold, also known as 24-karat gold. It is regarded as the purest form of gold available in the market.
However, 24-karat gold is extremely soft and is generally not used for intricate jewellery pieces. It is more commonly sold in the form of gold coins and bars.

How BIS hallmarking helps buyers
In India, gold jewellery is certified under the hallmarking system regulated by the Bureau of Indian Standards. A BIS hallmark confirms that the purity of the gold has been independently verified.
Modern hallmarked jewellery usually includes the BIS logo, a purity mark such as 916 or 750, and a six-digit Hallmark Unique Identification (HUID) code. The HUID allows buyers to trace and verify their jewellery.
While higher purity generally means higher gold value, the final jewellery price also includes making charges, wastage costs, and taxes.
