Gemstone Enhancement: History, Science and State of the Art
Editorial Reviews
Book Description
This is the second edition of Nassau's important work on the methods of modifying and enhancing gemstones and of treatments available to enhance the color and appearance of gemstones. This includes various types of irradiation and heat treatment, colorless impregnations, bleaching, dyeing, diffusion and other processes. Some of these processes date back at least two thousand years; others are of quite recent origin.
From the Publisher
The book covers such advances as glass and plastic filling of diamonds and other gemstones, the large expansion in the use of both heat and irradiation treatments and the efforts to keep up identification procedures with the advances in treatments. Gemstone Enhancement is written for gemologists to simplify their work; by knowing the details of the possible treatment techniques, the treatments that have been applied to the gemstone under study can be more readily recognized. Collectors, dealers, jewelers, appraisers, pawnbrokers and others interested in gemstones will also gain added insight from knowing the range of possible treatments. All the fundamental concepts are covered, so only a general knowledge of gems is required of the reader.
