This 3rd edition has 173 new photos, and it updates gem professionals on new treatments, jewelry styles, grading systems and geographic sources of' rubies, sapphires and emeralds. Using close-up photos, it shows how to make visual judgments about clarity, transparency, cut quality and brilliance. In addition, the guide helps readers understand lab reports and find appraisers and labs. Guidelines on detecting imitations and synthetic stones are also presented. As stated in a review of the previous edition by the Journal of Gemmology: "This is the book for anyone who buys, sells or studies gemstones and also for the casual reader. This style of book (and similar ones by the same author) is the only one I know which introduces actual trade conditions and successfully combines a good deal of gemology with them. Especially good are remarks on the influence of local lighting conditions - hardly ever mentioned elsewhere but profoundly affecting display and sales: color, taste, and preference are considered too and the purpose and effect of different cutting styles. As well as all this are all the details any gemologist would want. Last of all, the pictures are very good, and no Internet reproductions have achieved this quality so far. Buy it, read it and keep it."
