Until 1933 the refractometer and the microscope were the two principal tools in gem testing. Then B W Anderson introduced the hand spectroscope which became the third vital instrument for the UK gemmologist. This work contains Anderson's papers, and also contains chapters on the Pye spectrophotometer and on lasers.
