• Detailed Discussion Of Enhancements, Color And Cut Make This Guide Exceptional. 11 June, 2007
"Colored Gemstones" is a beginners' guide to gemstones that aims to help consumers understand what types of gems are available, what to look for in determining value, and how to go about doing that. This book does not oversimplify the subject as some guides for beginners do. Author and gemologist Antoinette Matlins gives readers some preliminary guidance on how to familiarize yourself with a gemstone using a loupe and how to determine if it is well-cut. Then it is on to Part 2, which constitutes the bulk of the book and is a fount of essential and fascinating information.
First, the "4 C's" of color, clarity, cut, and carat, with particular emphasis on color and cut and how they relate to one another. Sample laboratory reports on gems are provided, so we see what a lab report can tell the consumer. The chapter on synthetic gems and enhancement treatments is particularly informative. The author describes common treatments and provides a very useful chart of treatments by gemstone. The chart lists treatments for 34 gem groups and indicates which treatments are typically used, seldom used, whether they are stable, and whether the treated gemstones require any special care, including which should avoid ultrasonic cleaners. Information on color enhancement spans several chapters.
A chapter on fraud and misrepresentation lists which gemstone treatments are acceptable practice and which are dishonest, with descriptions of the treatments, and a list of deceptive names often used to mislead customers. So we will know what our options are, the author lists gems by color, provides a list of gems not routinely enhanced for those who prefer natural stones, and a table of how much treated vs a natural stones differ in price. There is a detailed price guide for 21 groups of (faceted) gems, indicating what you may expect to pay for good to extra fine quality stones, wearability, and availability. Opal and synthetic price guides are separate. One chapter is dedicated to descriptions of about 40 gems, with data on hardness, chemical composition, wearability, and brilliance for each. Ms. Matlins concludes with specific advice on what to ask and look for when buying stones, what facts to make sure appear on your receipt, and tips for cleaning and caring for gems.
Having read Renee Newman's Gemstone Buying Guide, I find that Ms. Matlins' "Colored Gemstones" is more complete. This is primarily because the coverage of enhancements, synthetics, and price are more extensive in this book. Its discussions of how cut affects color are also better. That said, the "Gemstone Buying Guide" treats star and cat's eye stones more thoroughly and has a slight advantage in coverage of opal and jade. It provides more vital statistics, including refractive index, cleavage, and specific gravity. "Colored Gemstones" biggest shortcoming is the scarcity of photographs. There is a 16-page insert of color photos, but most of the gems discussed are not pictured. The "Gemstone Buying Guide" has far more photos, but if you have to choose one book, I think you'll be happier with "Colored Gemstones" unless your interest is in cat's eye or star gems.

• Informative 15 January, 2007
Quite enlightening. Particularly liked the guide for prices of gemstones as well as the uses of stones. Had I purchased this book before, I would have made more informed choices when buying gemstones. Would recommend to anyone buying any type of gemstone.

I FOUND THIS BOOK TO BE VERY EDUCATIONAL, SINCE I AM STARTING TO PURCHASE JEWELRY ITEMS FROM JTV.COM WHICH OFFERS AN ARRAY OF THINGS THAT I HAVE NEVER HEARD OF, AND THIS BOOK IS A GREAT TOOL TO SMARTER GEM SHOPPING. I RECOMMEND PEOPLE READ THIS BEFORE MAKING A BIG JEWELRY PURCHASE.

• Informative But A Lot Of Repetition 24 May, 2007
If you buy Jewellery and gem buying guide from the same author, you find it is a lot of repetition. However, to me this book is giving more information than the other one as the discussion of more focus on gemstone.

There is a lot of good information in this book. However, it is not for someone new to the trade. Not many pictures to use while reading. makes it hard to follow certain parts of the text.
