In addition to the perennially successful Gemstones of the World, first published in 1976, he has authored Collins Guide to Rocks, Minerals, and Gemstones and Handbook of Rocks, Minerals, and Gemstones, among other authoritative rock and mineral identification guides. Lesser-known and rare gems are not neglected, however, and he has compiled a fairly exhaustive list of gemstones, complete with color, hardness, density, refractive index, crystal system, and chemical composition. These first few sections serve as an excellent introduction to, or refresher on, many of the basic concepts that help make identification easier.By contrast, this book is clearly laid out, informative, includes obscure/little known gemstones, and has good photographs.
