When Gold hallmark started in India?

The hallmarking of gold in India has a long history that dates back to ancient times. Contemporary gold hallmarking system in India was formally instituted by the Bureau of Indian Standards (BIS) in the year 2000.

Before the introduction of the BIS hallmarking system, India had a voluntary hallmarking system, but it was not regulated, and there were no strict standards or enforcement mechanisms. Due to concerns about the purity and quality of gold being sold in the market, the Indian government decided to implement a mandatory hallmarking system to protect consumers and ensure the authenticity of gold jewellery and other gold items.

On January 1, 2000, the Indian government launched the BIS hallmarking scheme for gold jewellery, making it mandatory for all gold jewelry sold in India to carry the BIS hallmark. The hallmark consists of the BIS logo, the purity of the gold (in carats), the logo or code of the assaying center, and the jeweler’s identification mark.

The hallmarking of gold has been gradually expanded to cover more cities and regions across India to ensure widespread implementation and consumer protection.
