Fantastic book!
This book is absolutely essential for the novice gemologist. It contains instructions for testing gemstones with the most commonly available instruments, and teaches you how to tell a natural stone from a man made one.

Great price
I can't really speak of the quality of these batteries, since I haven't used them yet, but the price was phenomenal.
