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.
Collector's Guide to the Garnet Group Paperback edition by Robert J. Lauf
Robert J. Lauf holds a Ph.D. in Metallurgical Engineering, and has conducted wide-ranging scientific research in fields ranging from nuclear fuel to microwave processing and biomineralization. He has been granted over forty U.S. Patents, and has written ten books on mineralogy for the collector.
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...
Over 100 vivid color photographs of beautiful feldspar minerals show each species in its geological context. The feldspar minerals, as a group, make up nearly sixty percent of the earth's crust. Large crystals are found at many locales worldwide, in both igneous and metamorphic rocks. Often, feldspar forms the matrix for stunning gem crystals found in pegmatites. This book explains how feldspars...

Superb examples are found at many locales worldwide, and in diverse geological settings from pegmatites to schists. Over 120 clear, crisp photos show each mineral in its geological context. This book will help mineral and gem collectors understand tourmaline mineralogy and see how...
Over 115 striking color photos display pyroxene group minerals in all their forms and colors. This group of rock-forming minerals is best known to collectors through well-formed diopside crystals from many localities, including in Canada, the northeastern United States, the Alpine regions of Europe, and through the gem-quality spodumene found in pegmatites from California to Pakistan. Spectacular...
Among rock-forming minerals, the zeolite group is large and widespread, and is enormously important to industry. Zeolites form excellent crystals. The group is structurally complex and notable for its ability to exchange cations with surrounding solutions. Numerous diagrams help visualize important structural features that define various framework types. Over 200 photographs of these beautiful...
