Best place in kolkata to learn about gems and it's quality

This is the best place to grade your Gems in Kolkata but because of theirs lack of awareness campaign people are getting fraud lab reports from various fake Gem Testing Lab's. Even some of them change the abbreviation of IGI as Indian Gemological Institute or GIA as Gem Identification & Authentication. It's sad that institutes like IGI & GIA doing nothing for Indian Gem market, whereas they are more active in America & European countries. It's little bit costly but again it's good to buy a natural gemstone than wasting money for a fake or synthetic one.
