Gemstones of the World: Newly Revised & Expanded Fourth Edition by Walter Schumann (Author). Gemstones of the World is the single, cornerstone volume that each hobbyist, jeweler, jewelry maker, and rockhound needs. And this updated edition comprises a new chapter on the treatment of gemstones, expanded information on what’s “New on the Market,” and 400 additional stones.
Greater than 1,500 full-coloration photographs showcase every valuable and semiprecious stone in its rough, natural, polished, and cut renditions. Every entry gives complete info on the gemstone’s formation, construction, bodily properties, and characteristics, along with the best methods of working, cutting, and sprucing it. There are even full therapies of lesser-known gems; a particular part on rocks as valuable stones; and natural gem materials. Charts and tables (including the “double fraction” figures that specialists need) help collectors determine unknown gems and test for genuineness.
I purchased this guide for my mom-in-regulation who loves gemstones. The ebook was a pleasant trying book. It had an excellent weight to it and it had attractive photos. It seemed to have much more data than among the other gem books I seemed at. I was more than happy with this purchase.
The new edition of this classic work adds material overlaying gem treatments and issues like diamond testing devices. It has several pages of "new to the market" gems, and updates and extends a few areas and has some minor rearrangements of the material. It is noticeably thicker than the 3rd version, but general it's pretty much a set of small enhancements moderately than anything revolutionary.
It remains probably the very best first ebook on gem stones for anybody interested in the subject. It tells you just a little bit about everything, though it generally does not cover any matter in nice depth. It's a pleasingly sized hard-bound quantity which could be very portable and fairly moderately priced.
There is a new six web page section on the healing powers of gems which I believed was moderately disappointing to see, however I guess they really feel the need to cater to the brand new-age audience as well.
It is a guide that everyone with an curiosity in gem stones ought to own, and the 4th version is a worthy update and a worthwhile improve for anybody who owns a earlier edition.
