Noted geologist G belin and freelance scientific writer Erni distinguish their work from other gem books by providing geological perspective. "The purpose is to guide the layperson into one of nature's most fascinating puzzles without any need for a specialist's knowledge." They accomplish this purpose through over 370 gloriously colorful photographs of gems and painstaking descriptions of their creation within the earth's crust. They focus on 18 clear gemstones, from diamond to zircon, and eight opaque "ornamental stones," from agate to turquoise. The authors present fascinating microscopic investigations of stones and comparisons with human-made gems; additional chapters cover jeweled treasures used by royalty and clergy, historically important jewels, plus gemstone lore. A subtle social message is conveyed through the contrast of luxurious finished jewels with photos and descriptions of actual gemstone mining and polishing by native workers around the world. Rich in beauty and content; recommended for public and academic libraries. Therese Duzinkiewicz Baker, Western Kentucky Univ. Libs., Bowling Green
