gemolology institute of America PDF Chapters

[Lyn]

Hi, just wondering if someone could help me. I have a pdf coloured stones chapter 8 written by the Gemology institute of America..
There are many other chapters that I am trying to source, but I cannot seem to find them. I cant remember what site I downloaded it from, or whether I could have accessed it through this forum. Could anyone help please.

Regards Lyn Best.
