This rare antiquarian book comprises a guide to collecting and identifying gem stones in Scotland. Gem stones are minerals, and their study must therefore be treated as a scientific subject. This book, however, is not intended to be a textbook of mineralogy, but instead as an accessible and useful tool to be used those who hope to collect precious stones in Scotland and who at the same time want to identify their finds for themselves. It also aims at telling them something of the natural history of our gem stones. This book comes complete with a number of detailed illustrations and diagrams, making it a great book for beginners and a must-have addition to any gemmological collection. This book has been elected for modern republication because of its immense educational value, and is proudly republished here complete with a new introduction to the subject.
