When I used to deal in selling of Gemstones and manytimes I came across people who had been cheated while purchasing Gemstones.

This cource on Gemology in written by Barbara Smigel, PhD, GG. which I am putting on my web site.

The main aim of keeping this information on internet is to give knowledge to people on how to select their Gemstone.
