Book excerpt: Practical Gemmology has for decades been recognized as the standard work for those learning how to identify gems and ornamental minerals. It is recommended by educational authorities as a course textbook, and it is also particularly suitable as a self-instructor for those entering or hoping to advance in the jewellery and gem trades, or for the keen amateur. The 21 sections comprise notes on the formation of gem materials, and a section on luminescence and electrical effects bring a more modern approach to this part of the subject. More information is given on the inclusions seen in gemstones, and the newer synthetic stones are discussed. The methods used in cutting gemstones and details of more of the unusual gemstones now cut and polished are also discussed.
