Summary Author: Antoinette Matlins and A C Bonanno Format: hardback, 380 pages 5th Edition Contents Setting up the lab, proper lighting for gem identification. Essential instruments, what they are and how to use them: the Loupe, the Chelsea filter, the dichroscope, the ultraviolet lamp, the refractometer, the Microscope. Optional instruments, when and how to use them: the spectroscope, the polariscope, the diamond-type spotter and blue diamond tester, essential tools for diamond buyers, the immersion cell, the electronic diamond tester, the carbide scriber, the synthetic diamond tester. Antique and Estate jewellery; Appendices Review A serious book about identifying gemstones, written by two professional gemmologists. Rather than work through a list of gemstones, there's a brief introduction to gemmology, then a list of gem testers, describing their features and limitations. The result is a complete set of instruction manuals for gem testers, a guide to the principles behind them...and by the time you've finished, you should be able to identify hundreds of gemstones.
