This second edition 'Gemmology' has been expanded and updated throughout by the well known writer and editor of Butterworth-Heinemann's gemmology series, Peter Read. This is a much needed update of a classic text and new syllabus information and sample examination theory papers for the Gemmological Association's Preliminary and Diploma courses are included. The additions also incorporate more recent developments, such as the introduction of synthetic moissanite and the De Beer's instruments for distinguishing between natural and synthetic diamonds.'Gemmology' still serves as a useful reference guide for gemmologists detailing the latest natural and synthetic gem materials and is an invaluable text for anyone in the gemmological profession.
