Title: Gem Testing
Description: London England, Heywood & Co, 1958. 6th Edition, Binding: Cloth, Very Good. 8vo - over 7" - 9" tall Hardback A full description, plentifully illustrated from photomicrographs, of the characteristic features of synthetic stones, doublets, and pastes, is interposed before the chapter on the use of the microscope, with which it should be read in close conjunction, as the most important function of the microscope from the jeweller's point of view is to distinguish between natural stones and their synthetic counterparts. A simple account of the spectroscope as used in testing coloured stones conlcudes the first section of the book. Illustrated. 334 pp.
