What a wonderful Gem of a book. I have lost count how many times I have been to Thailand on Holiday and this book is a wonderful find if you’re visiting this beautiful country, especially if you would like to purchase gems.
I wish I have this book years ago before I travel to Colombo. The book is easy to read and contains key information for a newbie to know before they buy anything in the tourist location.
Though tailored for the international tourist, this book is full of noteworthy resources for anyone seeking rock hounding adventures across the United States.
As a graduate gemologist, I was glad to see factual but easy to understand information about gems. A first time visitor to Thailand, I felt more confident while gem shopping in Chanthaburi.
