Gem-Stones and Their Distinctive Characters
George Frederick Herbert Smith
A diamond and a bit of glass can look alike until you measure how each one bends light. George Herbert Smith explains the science of gemstones, from total reflection to minimum deviation, and the traits that tell one precious stone from another. A clear guide to identifying gems by their true characters. For the mineral lover who wants to know what really sparkles.
Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
