Amit Sathe

Gemmological Institute of India has made a huge contribution to where I am in life today. The institute helped me a great deal to imbibe and inculcate a scientific temper towards the study of gemmology, whereas in a country like India, gemstones have always had an astrological element associated to them, rather than their aesthetics. Our teachers not only imparted the necessary knowledge but also reminded us time and again the importance of ethical practices, which resulted in them being engraved in my mind forever

The knowledge that we got in the institute is value-added for us and it’s really helpful not only for business purposes but to stand in the competitive market also. I feel proud that I am connected with the GII.

I was the first member of our family to undergo formal training in Gemology though our family business was more than 50 years old then I was fortunate to have attended the gemmology course of GII in 1984. I gained a lot of insight and knowledge which eliminated a lot of misconceptions about gemstones. As a member of the Forum of Indian Gemologists, I have always been able to keep my knowledge updated.
