Gemstones of the World

Translated by Evelyne Stern.

True-color photographs picturing gemstones, many in rough and polished states, with full details of where they are found, how they are mined and cut, how they are imitated, how they are identified and classified, what their characteristics and physical properties are.

When you purchase a new piece of jewelry, are you really sure you know what you are getting? How valuable or rare it is? Whether or not it might be an imitation? Here to help you is an authoritative guide to the world's gemstones with true-to-nature color photographs of over 1,400 specimens, many shown in both rough and cut states.
Although at one time jewelry represented wealth and power, today almost everyone can afford beautiful stones for jewelry, whether precious or semi-precious. On these pages you will discover what gems are, how they are formed, how they are classified and named, what their physical properties are, how they are pro-duced, cut, and polished--all told in language the layman can understand. There are special sections on: fabricated and synthetic gems; how to recognize gems by color; birthstones; organic gems such as coral and pearl. And, throughout, suggestions are made in the descriptive text on how you might confuse a specific gemstone with a similar stone or a synthetic or imitation.
Whether your taste in jewelry runs to diamonds and opals or to lapis lazuli and rose quartz, you will be able to acquire new pieces with an "educated eye" if you have this illuminating book at hand. (You might even find that that precious emerald brooch you treasure is really a pale beryl with an emerald skin!)
