This book is very practical! It's really helpful for people like me who are interested in Southern Red Agate but don't know much about it. It is rich in content, covering everything from basic knowledge to identification methods and market conditions. It feels like a caring friend who told me all the secrets about southern red agate. Moreover, the language in the book is easy to understand and not obscure at all, making it easy for people to understand. I think it is very similar to the book "Antique Guide", which is the kind of practical guide that allows people to learn real things by reading it.
