'...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
