Welcome to GTC

Since ancient times Patna is a very important place. At present it is the capital of Bihar but in the past it has seen its golden period as Patliputra. It is also the centre of trades in the state.

Since ancient time gemstones are in the roots of the human being. People use them in the jewellery and also use them astrologically. With the increase in the technology new gemstones, synthetics and treated products are attracting the people by its colour and beauty. Due to the modern technology stimulants and synthetics are so advanced that they are difficult to identify by the traditional methods. New technology is required to identify them.

In Bihar gemstone trade is increasing day by day but there was a big hurdle as there was no any scientific organization which can test, certify and authenticate the gem stones due to the lack of a trusted scientific lab. People have to travel outside the state territory for their inner soul satisfaction and for their trade needs.

Considering all these aspects we have introduced one of its first kinds Gem Testing Center (G.T.C) in Bihar in the last month of 2012.

We are not only working as the testing lab but also we are trying to aware people to know about the facts regarding gems.
