From Library Journal
Focusing on gemology as a science rather than a fine art, the authors have written an honest and straightforward book that lays the groundwork for identifying gemstones in an easy-to-read-and-understand volume. They outline useful information on setting up a lab, securing proper lighting, and identifying the essential and optional instruments used in successful gem identification. They also explain how to identify the myriad inclusions and blemishes found in natural and synthetic gemstones and devote a section to enhancement techniques found in antique and estate jewelry.
