This practical jeweller's manual has been the standard work on gem identification since it was first published in 1942. This updated and expanded edition adds descriptions of many new synthetic gems and treatments of natural gems, compares them with the untreated natural stones which they resemble, and suggests methods of distinguishing them. Includes 70 new color plates. Annotation c. Book News, Inc., Portland, OR (booknews.com)
