Detailed Discussion of Enhancements, Color and Cut Make This Guide Exceptional.

"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

Very thorough & informative

Everything I needed to know to get started buying gemstones. Easy to read and very detailed; it helped me learn where the true value lies in these gems. More than I ever thought I'd learn!

Great Information, Very Helpful

I'm a novice at gemstones, but I found this book easy to read. It had all the information I needed to shop for gems! I'm sure people with more experience would also find this helpful.

A 'must' reference, especially for consumers just starting out in gem collecting or investing

The second updated, expanded edition of COLORED GEMSTONES: THE ANTOINETTE MATLINS BUYING GUIDE is on the market and it's not to be missed for any avid gem collector. Here are all the basic keys to gems; from initial assessment of the factors which lend value to descriptive names, misnomers, facts on hardness and wearability and more. A 'must' reference, especially for consumers just starting out in gem collecting or investing. Diane C. Donovan California Bookwatch

Consumer Protection Advocate

One would not think that competing gemstones titles could generate the passionate allegiances found in the various on-line reviews of those titles. However those allegiances are there and I think I know why - have you ever noticed how people committed to exposing the truth are often reviled? In an industry where deception, rephrased as "enhancements" abound; where too many jewelers justify pawning off on unsuspecting customers something less-than-genuine as, "simply acknowledging reality" or "giving the customer what he wants", Antoinette Matlins stands out as an oracle of truth. This, I'm sure, makes her somthing less than heroic to those who enjoy the easy mark-ups in less-than-genuine articles. (Apparently Antoinette Matlins's father was something of a pioneer in stepping forward and informing the public about what really goes on behind the scenes in the world of gems.) If you have a passion for truth; are a dedicated and tireless advocate for consumers and consumer rights, and wish to protect yourself or someone you love from unscrupulous sharks in the gem trade, than obtain and read this compact, easy-to-read volume. While there may be other volumes on the market with more breadth and scope, and more abundant pictures, I felt very satisified, after reading this book, that I had gained a solid understanding with which I could begin the perilous navigation of the gem trade.
