The Spectroscope and Gemmology
by Basil Anderson and James Payne
Soft cover, 6" x 9", 269 pages, copyright 2010

The Spectroscope and Gemmology is the first book devoted exclusively to the spectroscope and its use in gemstone identification. Until 1933 the refractometer and microscope were the two principle tools in gem testing. Then B.W. Anderson introduced the hand spectroscope which quickly became the third vital instrument for the UK gemmologist. The publication of Anderson's papers in the mid -1950s alerted gem laboratories world wide to the importance of this instrument. Today its use is universal.

Anderson and his life long colleague, Payne, both of the world's first full-time gemmological laboratory, were the pioneers in recognizing the vast potential of the spectroscope for this purpose. The Spectroscope and Gemmology, as the extensively edited, updated and enlarged version of Anderson's original papers, provides a vital textbook wherever gemmology is used or taught. The distinguished gemmologist R. Keith Mitchell has undertaken the editing and has added chapters on the Pye spectrophotometer and on lasers. He has also reproduced new line drawings of spectra in three aspects to accommodate the prism instrument in both the British version and that favored by American gemmologists, and in another version as seen through the diffraction grating instrument.

Written for gemmologists everywhere and incorporating the latest developments this book will prove indispensable to all engaged in gemstone identification. The Spectroscope and Gemmology is organized into two major sections, The History and Development of Spectroscopy and Absorption of Gem Materials. A 5 page appendix provides references and notes. The History and Development of Spectroscopy covers 'The Celebrated Phenomena of Colours', The Yellow Lines of Sodium, The Absorption Spectra of Solids, Other Uses of the Spectroscope, Emission Spectra, The Quartz Spectrograph and The Spectrophotometer.

Absorption of Gem Materials covers Absorption Spectra, Light Sources - The Causes of Color, Absorption and Fluorescent Spectrum of Ruby, Absorption and Fluorescent Spectrum of Red Spinel, Absorption Spectra of Pyrope and Topaz, Absorption Spectrum of Emerald, Absorption Spectrum of Alexandrite, Absorption Spectrum of Jadeite, Absorption Spectrum of Demantoid Garnet, Other Chromium Spectra, Absorption Spectrum of Almandine Garnet, Absorption Spectrum of Blue Spinel, Absorption Spectra of Peridot and Sinhalite, Absorption Spectra of Enstatite and Diopside, Absorption Spectra of Kornerupine and Axinite, Absorption Spectra of Absorption Spectra of Green Tourmaline and Iolite, Absorption Spectra of Idocrase, Actinolite and Serpentine, Absorption Spectra of Sapphire and Chrysoberyl, Absorption Spectra of Aquamarine and Orthoclase: Spodumene and Jadite, Absorption Spectra of Andradite and Epidote, Absorption Spectra due to Manganese, Absorption Spectra due to Cobalt and Vanadium, Absorption Spectra due to Copper: The Spectrum of Turquoise, Absorption Spectra of Zircon, The Rare Earth Elements, Absorption Spectra of Diamond, Miscellaneous Spectra, Absorption in Synthetic Gemstones, Absorption Spectra of Glasses, Fluorescence Spectra, and Summary of Absorption Spectra.
