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.

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.
