Gemstones - Robin Hansen

A brilliant book for anyone starting out with gemstones. Covering everything from crystallography to charts of constants. Written in a charming and non boring fuddy duddy way.

Not only for those now to the field, it is an excellent concise, portable, all round book for gemmologists.

Kerry was honoured to read the book before publishing so knows exactly how good it is. We use it here as our reference book in class.
