A new chapter on diamond-grading reports helps the reader know what to look for on a report, but with a warning that not all grading labs are equal. A chapter on gold, platinum and palladium helps the consumer decide on the characteristics they prefer in their setting, accompanied by terminology pertaining to precious metals. The benefits and cautions of 14-ct vs. 18-ct gold are compared, as are the pros and cons of the different metals. A new chapter on silver has been added, explaining its history and standards. It includes a review of various brand names of silver that have been treated with anti-tarnish alloys such as those containing copper or germanium. Another new chapter covers alternative metals, which are quickly finding acceptance on the marketplace. Short descriptions of each metal are accompanied by a discussion of their advantages and disadvantages, including stainless steel, tungsten, tungsten carbide, titanium, cobalt-chrome and tantalum.
A chapter on setting styles describes popular mounting techniques, including prong, channel, bezel, bead, pavé, flush and bar settings, along with invisible setting, a method of displaying stones without visible metal support. New to this edition is a section with tips on what to look for in a well-made, secure setting. Selecting a ring style is also a personal choice, but the author poses practical questions to consider when choosing such a significant piece of jewellery. The next chapter covers how to clean and store a diamond, along with how to prevent it from being switched. The latter entails knowing your diamonds unique characteristics and establishing a long-term relationship with your jeweller. The book concludes with a chapter that gives shopping pointers, followed by a new section on the chemical, physical and optical properties of diamond and a thorough bibliography. This book can be used by consumers who are not necessarily interested in becoming diamond experts, but who want to feel more informed about the material and the industry in general when considering a purchase. The book is also a helpful sales tool for those in the retail jewellery industry.
It outlines what a consumer should know and what information a salesperson should be responsible for. The numerous updated photographs help illustrate current styles, and the streamlined text addresses commonly asked questions and concerns. -- THE JOURNAL OF GEMMOLOGY, 37(3), 2020.
