GSI not put the image of gemstone in issued test report, So, there are not proper traceability even not mentioned the size/ mesurment of stone. So, any gem seller can do dublicate certificate by given best quality gems. ** This test house not provided good quality of test certificate

Great place to visit for authentication of gemstones and diamond ,it is valued for certification

Best for gemstone testing in Kolkata. Affordable and trusted government certified lab report have be given for many years.For my emerald testing they charged Rs1204 where igi kolkata asked for Rs6500 for emerald testing. Nowadays where mostly fake gemstone sales people must test before wearing. GSI kolkata lab is very good and reputed. Submitted your gemstone before 1pm and get report in 2 days. There also OTS (on the spot ) test service for extra money. Go with a ID/addhar card.Its beside Indian musiam kolkata.

The scale and the breadth of work by this august institution defies imagination. It is practically impossible to find so much geological expertise under one umbrella as the Geological Survey of India!

Nice place.. All staffs are well behaved.. Quick delivery of Gem Stones..price is very reasonable.. Come on or before 11 am & give sample of stones till 2 pm.. Then get delivery of that on the same day with little higher price or get that delivery after 2 days after 4 pm.

One of it's kind in India. Repository of priceless specimens of Indian and foreign Meteorites....the repository is kept open on specific days for public viewing. GSI being the premier geoscience organization in India is the nodal agency and custodian of all these meteorite specimens
