Richard M. Pearl, a graduate of the University of Colorado and Harvard University, is a Professor of Geology at Colorado College. The author of twenty-one books about the mineral world (translations have appeared in French, Japanese, Russian, and Persian), he is a contributor to four encyclopedias and has written more than 300 articles for scientific, trade, and popular periodicals.

International recognition has come to him from gem and mineral organizations in thirteen countries. Professor Pearl is a well-known lecturer to both laymen and science teachers and has been active as founder or co-founder and past-president of the American Federation of Mineralogical Societies, the Rocky Mountain Federation of Mineralogical Societies, and the Colorado Mineral Society. He has collected and prospected in nearly every state and province in the United States and Canada. A Fellow of the American Association for the Advancement of Science, the Meteoritical Society, and the Gemmological Association of Great Britain, he is a past- president of the Southwest Section of the National Association of Geology Teachers.

The mineral and gem hobby continues its amazing growth— especially in the United States and Canada, but also throughout many other parts of the world.

 Active rockhounds, mineral collectors, and amateur lapidaries are numbered in the hundreds of thousands in America alone. Millions more are interested enough in these activities, of which they have seen and heard so much, to justify this book. Its purpose is to define, explain, and describe the most essential subjects in this fascinating realm of science and nature.

In this handy-size book are also included important and interesting names and terms that you will need when learning about minerals, crystals, gems, the art of gem cutting, rocks, mining, meteorites, and the basic mineralogy and geology that underlie the entire field. Most of the subjects follow an alphabetic, encyclopedic style, and each is a concise definition. The minerals and gems are described individually, and in this section is included a selection of the curious and obsolete names often encountered in the literature.

Related material is treated differently where desirable; there are short essays on mineral collecting, identifying minerals, the lapidary art, and the origin of mineral names, and information about the classification of .meteorites and falls of unusual interest. The superb color photographs by Reo N. Pickens, Jr., are among the finest ever made. They have been selected to show the features of the mineral kingdom in such a way as to inform and instruct, as well as to delight. The drawings, made by Christopher D. Wadsworth and Mignon Wardell Pearl, have been carefully chosen for their educational value. So too have the black-and-white photographs, credit for which appears in the acknowledgments. The author’s thanks are also clued to Mrs. J. V. Winters for assistance and to Chester H. Johnson, a former student of the author’s and now Science Editor of Western Printing and Lithographing Company, for generous encouragement and cooperation.
