I'd been looking for a book like this for what seemed like FOR-EV-ARRRR!!!
As a jewelry artist, I've always wanted to add some gemstone books to my huge jewelry-related book collection, but all I could ever find were ones that seemed to be written only for gemstone collectors & science nerds--not that there's ANYTHING bad about stone collectors OR science nerds--it was just that these books never really focused much (if at all) on the jewelry-related aspect of gemstones!!
This book definitely fills that huge (and what you'd think would be obvious) void that all those other books seem to have missed.
I am hoping the book will be revised in the future to include more stones, and maybe fix a few things that were left out..
For example: in the list of U.S. locations where Tourmaline mines exist, Maine was left out!! :-o
But the flaws I see in this book are very minor--overall I am very satisfied with it, and I am very thankful to Judith Crowe for finally making the book that I was searching for!! :-)
