内容説明
"Gemstones of the World" is the single, cornerstone volume that every hobbyist, jeweller, jewellery maker and rock-hound needs. This updated edition contains a new chapter on the treatment of gemstones, expanded information on what's 'New on the Market' and 400 additional stones. More than 1,500 full-colour photos showcase each precious and semiprecious stone in its rough, natural, polished and cut renditions. Each entry offers complete information on the gemstone's formation, structure, physical properties and characteristics, along with the best methods of working, cutting and polishing it. There are even full treatments of lesser-known gems; a special section on rocks as precious stones; and organic gem materials. Charts and tables (including the 'double fraction' figures that experts want) help collectors identify unknown gemstones and check for genuineness.

The new Fourth Edition
2009/11/26
形式:ハードカバー|Amazonが確認した購入
The new edition of this classic work adds material covering gem treatments and things like diamond testing devices. It has several pages of "new to the market" gemstones, and updates and extends a few areas and has some minor rearrangements of the material. It's noticeably thicker than the 3rd edition, but overall it's pretty much a collection of small improvements rather than anything revolutionary.
It remains probably the best first book on gemstones for anyone interested in the subject. It tells you a little bit about everything, though it generally does not cover any topic in great depth. It's a pleasingly sized hard-bound volume which is very portable and quite reasonably priced.
There's a new six page section on the healing powers of gemstones which I thought was rather disappointing to see, but I guess they feel the need to cater to the new-age audience as well.
It's a book that everyone with an interest in gemstones should own, and the 4th edition is a worthy update and a worthwhile upgrade for anyone who owns a previous edition.

Essential reference... beautiful little book!
2010/4/26
形式:ハードカバー|Amazonが確認した購入
I am a mineral and crystal dealer and love this "gem" (sorry) of a book. It is well-organized and clearly written, and the photographs are actually useful - showing specimens that one might actually see - making it valuable for identification. Useful for all levels of knowledge or interest, with enough depth for a professional reference, yet not daunting for a novice. High-quality printing on glossy paper and a very portable size - this are a must-have for the enthusiast, collector, or anyone who loves gems, minerals, and crystals.
