A SPARKLING RESOURCE. The new 3rd Edition of the Diamond Handbook is more advanced than ever before with updated information and photos on everything you need to know about identifying and evaluating diamonds. Highly recommended for professional gemmologists and those with a specific interest in diamonds, this book features need-to-know information, covering basic diamond facts, price factors, treatments and methods of detecting synthetic diamonds. Notable additions are colour images of diamond spectra, a chapter on detecting transparent and black diamond imitations, and updated photos in the chapters on fancy colour diamonds and antique diamond jewellery. Most importantly, the author has updated the previous edition (published in 2008) to reflect major changes in the diamond trade, so even if you are already lucky enough to own a copy it is well-worth investing in this newer edition.- Summer 2018 issue of Gems & Jewellery, which is published by the British Gemmological Association (aka Gem-A)
