FROM DIRECTOR'S DESK
I am really passionate about gems! And this love dates back to my University days. Soon after obtaining my Masters in Geology from Panjab University, Chandigarh, I felt the pull towards gemstones from my favorite stream of Mineralogy.
So here we are, trying to make gemologists and diamontaires of all those wanting to get “rocks in their heads”.
