Hallmark is a mark which is applied on a precious metal and considered as a guarantee of purity & fineness. In India, there are two metals which are taken under hallmarking scheme i.e. Silver & gold. The hallmarking scheme is started by Bureau of Indian standards. BIS certified jewellers can get their jewellery hallmarked from any of the recognized assaying & hallmark Centers of BIS. Hallmark is the accurate determination & official recording of the proportionate content of precious metal in silver or gold.
Now days, government is also giving final touches to the mandatory hallmarking of jewellery. Hallmarking is permitted in only 3 categories-
Some jewellers are currently selling non-hallmarked jewellery whereas many jewellers in town and rural areas are selling hallmarked along with non- hallmarked jewellery. BIS warned jewellers that a jeweler who is not having the valid certificate of registration cannot sell hallmarked jewellery and if any individual still catched using BIS logo and keeping hallmarked jewellery , it will be considered as an offense and a strict action will be taken against him. BIS recently issued a notice and said that non-licensed jewellers should stop using the BIS hallmark logo on the jewellery, display board and on packing material.
There are 750 hallmarking and assaying centers in the country and 100 is currently in the process of establishing.

Process of Assaying and Hallmarking
The process of assaying and hallmarking is as follows –
In the first step, jewellery receipt and article wise segregation takes place.
In the second step, jewellery will be checked for homogeneity of the lot by XRF.
In the third step, take a small sample (250g) from the article in order to do Scraping/Micro dwelling/cutting.
In the fourth step, weight the jewellery accurately and after doing the weight, wrap the jewellery in lead foil with some added silver.
In the fifth step, verify the sample as per IS 1418 by applying the fire assay method. Fire assay method is a method in which gold or silver can be refined or assayed in a furnace at about 1100 degree Celsius. It removes all base metals. Place the resulting gold-silver alloy button in nitric acid in order to dissolve the silver. The result we will get is pure gold.
In the sixth step, we reweight the resulting pure gold and in case the sample passes the test. The particular lot is hallmarked by laser marking and returns back to the jeweller.
If in any case, the sample is unable to pass the fire assay method, jewellery lot is returned back to the jeweller without hallmarking.
