We are providing all services with Hallmarking and assaying 


Hallmarking is the accurate determination and official recording of the proportionate content of precious metal in gold. Hallmarks are official marks used in many countries as a guarantee of purity or fineness. History of hallmarking dates back to 1300 AD, when a statute of Edward 1 instituted the assaying and hallmarking of precious metals, indeed hallmarking is the oldest form of customer protection. Government of India took the cognizance and understood the necessity of protecting the public in its purchases of gold jewellery, resulting in introduction of gold hallmarking in the country. RBI identified Bureau of Indian Standards as the sole agency to operate hallmarking in India. Accordingly, after in depth study of national and international practices, hallmarking scheme of gold jewellery was launched by BIS on 11 April 2000. .
