I gained a lot of insight and knowledge which eliminated a lot of mis-conceptions about gemstones. As a member of Forum of Indian Gemologists I have always been able to keep my knowledge updated.

Further taking inspiration from me another 5 members of my family including my wife and both sons have also taken the gemmology course of GDL.
