... this is the book I have been waiting for. It is an affordable, excellent reference book with every diagram and chart necessary for the identification of gemstones and gem material. Jewellery Time, April 2000 Reviews of first edition: 'Gemmology is a most welcome update and expansion of his Beginner's Guide to Gemmology...It fills a gap in practical gemmological literature' - Gemmological Newsletter '...it is clearly well-written, factually sound, well illustrated, and combines the virtues (and fortunately avoids the mistakes) of its acknowledged predecessors such as Webster's 'Gems', Anderson's 'Gem Testing', and the GAGB's teaching notes...Well done Peter. This book is a most useful contribution to the literature and can only assist Australian student of gemmology' The Australian Gemmologist 'This readable book on gemmology is slanted to both beginning and advanced students of the science of gemmology, and like Read's previous book on this subject will probably become a standard text.'
