BIS Hallmark
The Bureau of Indian Standards is a reliable body that certifies the quality of gold that is brought to you. Any gold that is certified in their laboratories will have their logo stamped on it. It is important before buying any gold bracelet, or necklace that you must check for its purity.

Purity in karat
Purity of gold is measured in karats; 24 karats is supposed to be the purest form of gold but it is too soft to be converted into jewellery so it is mixed with zinc or silver and then converted into jewellery.

Fineness of Gold
Fineness number is another way to calculate the purity of gold. It is the measure of purity in parts per thousand. Total purity should measure in 1.0, but it always has some impurities and is 999.9 parts per thousand.

Hallmarking Centre’s Mark/Number
When buying gold necklaces, earrings or gold bracelets for women, it is necessary to check the BIS hallmark and cross check the laboratory on their website. Only licensed laboratories of BIS are credible sources that can check the purity of gold.

Jeweller's Identification Mark
The jewellery shop from where you are buying your jewellery will also put its own logo on your gold jewellery. This could be the mark of the jewellery manufacturer or the BIS. The BIS has put up a list of jewellers on its website that are certified by it.
