History Of Gold

An attractive and highly valued metal, gold has been known for at least 5500 years. Gold was first discovered as shining, yellow nuggets. Its brilliance, natural beauty, and luster, and its great  malleability and resistance to tarnish made it enjoyable to work and play with. 

Pure gold is soft and is usually alloyed with other metals, such as silver, copper, platinum or  palladium, to increase its strength. The refined gold is then transformed into beautiful ornaments or used in high-tech industries such as automotive, electronics, medicine etc. Jewellery is the key element in the story of gold and India is the world’s largest market for gold jewellery.

Gold Purity

24-carat gold is fine (99.9 per cent Au w/w), 18-carat gold is 75 per cent gold, 12-carat gold is 50 per cent gold, and so forth. Gold is a relatively soft metal and high-carat gold tends to be easily damaged hence the 24 carat gold jewellery needs to be carefully maintained. Usually copper or silver is mixed with gold to make the jewellery.

Karat Measure Gold Purity
24 Karat  100% Pure Gold
22 Karat 91.7% Gold + 8.3% Other Metal(s)
18 Karat 75 % Gold + 25 % Other Metal(s)
14 Karat 58% Gold+ 42% Other Metal(s)
10 Karat 42%  Gold+ 58% Other Metal(s)

Diamond Purity

Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth.  In the diamond industry, even a fraction of a carat causes remarkable cost difference and hence precision is crucial. In the gold industry carat stands for the percentage of pure gold in a jewellery piece. The higher the carat, the higher the gold content. Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. GIA, Gemological Institute of America is the Largest, Most Respected Nonprofit Source of Gemological Knowledge in the World.

Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world.



Hallmarking in simple terms is a quality assurance certification that guarantees the purity of gold or silver. In India the system is BIS Hallmark which certifies that the piece of jewellery adheres to a set of standards laid by the Bureau of Indian Standards (BIS). The hallmarking is done at the BIS Authorized Labs where the gold or silver in every piece is individually tested for its purity and if found correct, a mark is put on it by laser machine.

The BIS Hallmark for gold jewellery consists of the following components- The BIS logo, a three digit number (out of a set of six pre-defined values) indicating the purity of the gold in part-per-thousand-format, logo of the assaying centre and a code denoting the date of the hallmarking.
