I love gems. I have a Graduate Gemologist degree (in addition to a physics degree). I do some high-end faceting and purchase gems and rough for faceting, jewelry making and simply for fun. My lab capability is better than that of most jewelry stores.Schumann's Fourth Edition has been a mainstay of my reference library. I just got his new 5th edition. Outside of an additional chapter on metaphysical attributions of gemstones, it's substantially similar to the previous edition although many updates are interspersed throughout the text and a few mistakes in the previous edition have been corrected. Oddly, the preface inside says "Preface to the 16th edition!"This has been a valuable and well-organized reference book complementing other materials for gemstone identification. It often has more information than other texts about the stones themselves, but doesn't try to be a specific identification manual, especially on separating natural/synthetic. It has a lot of good information about the various properties of gems, a small amount on mining and a good overview of production methods. The entries for common gemstones are quite complete, but it also covers a very wide range of less common stones and materials that are more recently commercialized. This work should be in the library of any gemologist. It's also simply a good reading book, with interesting information throughout the entire work.I find the new metaphysical chapter an eye-roller for me. As my daughter says, "gemstones definitely are metaphysical - playing with them makes me happy!
