Gems  2008-06-02
This was a good book, explained many aspects well. Sometimes a little hard to follow. Written for the experienced buyer.
great information 2007-12-28
This was just the book I was looking for. I just recently started to get into collecting colored gemstones and this book was full of great information on what tools I would need and how to use them. That was so important to me.
Essential Reference for Consumers, Hobbyists, Jewelers Interested in Gemstones.  2007-07-18
"Gem Identification Made Easy" opens up the world of gem identification to the jeweler, hobbyist and the curious. I didn't come away with the impression that gem identification is easy, but that some kinds of identification are easy, inexpensive and FUN! Antoinette Matlins makes it clear that the bar to entry into gemology is low. Practice, diligence, and three small instruments that cost less than $200 will enable you to identify 80% of colored gemstones and their look-alikes as well as diamonds and most of their imitations. Since there are at least 3 different gemstones on the market in every color and no shortage of synthetics and enhancement treatments, the skills within the pages of "Gem Identification Made Easy" are invaluable to anyone shopping for gemstones. If gems fascinate you, this book will help you discover if you would like to pursue gemology as a career or serious hobby.
The bulk of "Gem Identification Made Easy" are descriptions of the instruments involved in gem identification, detailed instructions on how to use each, and what they can show you, including many charts which will help you identify stones. The 3 essential instruments that everyone will need are: loupe, Chelsea filter, and dichroscope. The loupe magnifies the stones, revealing inclusions, blemishes, and fillers. The Chelsea filter differentiates between some gems and synthetics. The dichroscope distinguishes single-refracting stones from double-refracting and allows identification of stones by the colors they exhibit. In addition, Ms. Matlins provides instructions for additional tools that one would need to set up a lab: UV lamp, refractometer, microscope. Less essential: spectroscope, polariscope, and immersion cell. For diamonds: SSEF diamond-type spotter and electronic diamond tester. These could cost nearly $3000, but shopping on eBay will bring the price tag down.
The author also dedicates a chapter to "Antique and Estate Jewelry", in which she discusses imitation and alteration techniques frequently found in antique and period jewelry. She advises on how to detect them and includes tables of synthetics and imitations, when they appeared on the market, and characteristics that will help identify them. This is followed by many useful Appendices: a list of gems and look-alikes by color, gem hardness, specific gravities, refractive index tables, tables of dispersion and birefringence, glossary of terms, list of organizations offering gemology workshops or training, equipment suppliers. These are in addition to the many tables and lists in the instrument chapters. Color photos are limited to a center insert, where there are photos of gemstone inclusions and a few other identifying features. "Gem Identification Made Easy" is an easy to understand, practical entry to the fascinating world of gemstones.
Valueable book for gem id 2007-05-24
Love it so much. A lot of information. This book will teach you how to setup a lab and making identificaiton of the gemstone without attending the gemology school - with very very reasonable price.
Needs More Detail 2007-04-04
The book was good for a primer on gem tools and iidentification but lacked the detail I was seeking. It is an very good book for the beginner for it covers a lot of subjects about gem and the various tools used to identify them. I was seeking more exact detail and this book did not have it.
