Garnet, with its many color varieties, is a favorite of both mineral collectors and gemologists. Superb examples are found at many locales worldwide, in both igneous and metamorphic rocks. Other members of the group are prized by species collectors and micromount enthusiasts. Over 120 color photos of these beautiful minerals show each species in its geological context. This book also explains how garnets are formed and the unique conditions that create fine crystals and vivid colors. After a brief introduction, the general treatment begins with an explanation of the chemistry and taxonomy of the group. A section on their formation and geochemistry explains the kinds of environments where garnets are formed. Detailed entries for each mineral provide locality information and full-color photos so that collectors can see what good specimens look like and which minerals one might expect to find in association with them. An extensive bibliography is provided.

With the tremendous growth of population in this and neighboring states, there are more collectors than ever before and with the rapidly escalating prices for mineral and fossil specimens in the retail market, there is a great demand for displayable material. It has become necessary for professional geologists, hobby collectors, and commercial collectors to recognize each others existence and to try to work together within a framework of regulation, courtesy, and common sense so that material of scientific value is not lost and undue restrictions are not placed upon collecting. There is a continuing need for collectors and professionals to work together with resource managers and legislators to develop workable laws and rules affecting the collecting of minerals and fossils. This publication contains details information about collecting areas, divided by county to make for ease of use. Each collecting area contains information about the minerals, rocks, or fossils present, map recommendations, and other helpful tips on getting to the sites.

Unlike the dense and highly technical academic tomes that are text-heavy, poorly organized and intimidating, this colorful and easy-to-use reference guide dedicated to collecting rocks, gems and minerals is ideal for readers who want to expand their understanding without getting lost in a labyrinth of science. Beautifully illustrated with 700 color photographs providing wonderful detail and smartly organized to take the hassle out identification, you will enjoy the simplicity of the guide and the enthusiasm and knowledge of author Patti Polk, one of the top agate collectors in the world and a self-proclaimed "rockhound." You will also enjoy two areas that our competitors don't bother with. First it includes values, and second, it covers an introduction to lapidary, which is the cutting and polishing of rocks and gemstones for jewelry or display.

Quartz is prized by both mineral collectors and lapidary artists. Over 130 vivid photographs of these beautiful minerals are presented to show each mineral in its geological context. Superb examples are found in diverse geological settings from pegmatites to Alpine clefts and hydrothermal veins. The silica minerals are chemically simple, yet structurally complicated. Several high temperature and high pressure polymorphs are known. In addition to the polymorphs of silica, this book treats related minerals, including: lechatelierite, opal, and two natural clathrates, chibaite and melanophlogite. After a brief introduction, the general treatment explains the chemistry and taxonomy of the group. A section on their formation and geochemistry describes the kinds of environments where these minerals are formed. Then, entries for each mineral provide locality information and full-color photos so that collectors can see what good specimens look like and which minerals one might expect to find in association with them. An extensive bibliography is also provided.

Granite pegmatite crystals have long been admired by gem and mineral collectors as a source of fine specimens and gem materials. Pegmatites can host important deposits of ore minerals and industrial commodities, such as feldspar and mica. Their physical and chemical complexity presents daunting challenges to researchers who seek to better understand their nature and origins. With 209 stunning color photos and clear, authoritative text, this book provides a thorough discussion. Chapters cover pegmatite forms and distributions, interior structures, crystal, mineral, and gem pockets, and references for further study. Examples are from North America as well as worldwide.
