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.
