This early work on gemmology is both expensive and hard to find in its first edition. It contains a comprehensive account of the varieties of precious and semi-precious stones and their characteristics. This is a fascinating work and highly recommended for anyone interested in the subject of gemmology. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
