This treatise, "Treatise on Gemstone Identification," authored by Sutton Press and attributed to Anderson, serves as a comprehensive guide for the identification of precious stones. Published in April 2013, this English-language reference book, presented in EPUB format, is intended for jewelers and antiquarians. Its purpose is to facilitate the accurate identification of a wide array of gemstones, providing essential knowledge for professionals in the field.
This manual meticulously covers the fundamental principles and practical techniques required for gemstone analysis. It details methods for measuring refractive index, detecting double refraction, and utilizing color filters and the dichroscope. Furthermore, the book addresses the measurement of specific gravity, the differentiation of synthetic and imitation stones, and the application of microscopy. With detailed sections on identifying specific gems such as diamonds, rubies, sapphires, and emeralds, alongside a broad range of other stones and organic materials, this treatise is an indispensable resource for accurate gemological assessment.
This unusual work is a complete treatise on the identification of precious stones that is thoroughly recommended for inclusion on the jeweller or antiquarian's bookshelf. Contents Include: Preface; How to Use The Book; Refractive Index and its Measurement; Double Refraction and How to Detect it; Colour, Colour Filters and the Dichroscope; Specific Gravity and How to Measure It; Detection of Synthetic and Imitation Stones; The Use of the Microscope; The Identification of Diamond; The Identification of Ruby; The Identification of Sapphire; The Identification of Emerald; Aquamarine and Alexandrite; The Identification of Zircon; The Identification of Topaz; The Identification of Pink, Mauve, etc. Stones; The Identification of Brown and Orange Stones; Quartz, Opal, and Garnets; Tourmaline, Peridot, and Spinel; Identification of Translucent and Opaque Stones; Amber, Tortoiseshell, Coral, and Jet; Pearls: Real, Cultured, and Imitation; Appendix: Glossary, Alphabetical Summary of Gem Species, Crystal Systems, Bibliography, Specific Gravity and Refractive Index Tables; Names and Addresses of Recommended Suppliers; and an Index. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
