The Spectroscope and Gemmology
Basil Anderson & James Payne Edited by R. Keith Mitchell, F.G.A.
6 x 9, 288 pp, 75+ b/w illustrations, Quality Paperback , 978-0-943763-52-1
The first book devoted exclusively to the
spectroscope and its use in gemstone identification.
Until 1933 the refractometer and the
microscope were the two principal 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 worldwide to the importance of this
instrument. Today its use is universal.
Anderson and his lifelong 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, and 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 in that favoured 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.
