"the book I wish I would have had five years ago when I started at Rapaport."

Sonia Esther Soltani, Editor in Chief, Rapaport, posted on her Facebook page


A comprehensive new book from gemology expert Renée Newman covers every facet of this beloved gem, making it a perfect read for newcomers and veterans alike.

Gemologist Renée Newman is well-known in the trade for her practical handbooks. Her manuals on how to buy gemstones, pearls and diamond rings are classic references for industry members and keen collectors. Her latest publication is Diamonds: Their History, Sources, Qualities and Benefits, and it would not be hyperbole to call this book the bible for diamond knowledge. The coffee-table-size volume takes the reader on a fascinating journey covering the symbolic power of diamonds through the ages, the various mining levels, provenance, the evolution of cutting, and jewelry styles. It also tackles issues such as pricing, ethics and lab-grown diamonds. And to make sure she’s left no stone unturned, she closes her exhaustive guide with the emotional significance of these sparkling gems. Diamonds is the gift every newcomer to the industry should receive or buy for themselves. It’s also an essential read for consumers who want to make informed choices.

This could be the shortest book review ever. If you are interested in anything and everything about diamonds you need this book. Period.
     Renée Newman is a highly respected Graduate Gemologist and author of several acclaimed guides to gems and jewelry, including previous books on diamonds. But this latest book goes well beyond anything she has previously published on the King of Gems. She begins with a clear explanation of what a diamond is, starting with its use as a drill bit in India in the fifth century BCE and into modern times with a well-illustrated history of diamonds in jewelry. The chemical structure that distinguishes super-hard diamond from its super-soft cousin graphite is covered well. Also explained well are the atomic inclusions that create colored diamonds. Then the countries where diamonds are found are examined in roughly chronological order and with the very latest information, maps, and illustrations, many of them full page.
      Cutting and polishing diamonds took a while to get started-- not until about the mid-1300’s-- because of diamond’s extreme hardness. The evolution of diamond cutting is covered, all the way from primitive point cuts and table cuts, though the ubiquitous 58-facet brilliant cut, and on to today’s modern cuts. Again, superb illustrations and clear writing make everything easy to understand, and the various cuts are beautifully shown in jewelry from all periods.
      The evolution of diamond jewelry is treated in its own chapter, along with romantic histories, gorgeous photographs, and brief explanations of the different periods and styles. This chapter will be of immense interest to ASJRA members.
      The tricky subject of diamond pricing is covered in a dedicated chapter with a thorough (and thoroughly illustrated) discussion, especially of color and cut. Next is an in-depth treatment of laboratory-grown or synthetic diamonds, from Henry Moisson’s pioneering experiments up to the very latest of today’s commercial techniques.
      Of course diamonds have uses other than in jewelry, and a brief chapter at the end of the book covers these as well. However, this is principally a book about diamond jewelry and will be of prime interest to jewelry aficionados and historians. The writing is crystal clear, the numerous illustrations are superb, and the information provided is absolutely up-to-the-minute. Whether your interest in diamonds is casual or intense, you need this book.

The first thing you notice and appreciate about Renée Newman’s new book Diamonds: Their History, Sources, Qualities, and Benefits is the remarkable photo illustration that graces the cover: a group of five absolutely delicious-looking diamond rings. This photo is the perfect reminder of just how wonderful and aweinspiring diamonds can be, from the icy colorless gems to the candy-like fancies. But this is not just another coffee table book full of incredible images of impossibly expensive baubles (although, those are quite lovely!). In 272 glossy pages, Ms. Newman invites us to consider everything there is to know about diamonds, from their formation deep in the earth, to their mining by man and machine, and on to their eventual use in both industrial and entirely frivolous applications.

      Organized into an economical eight chapters, Diamonds takes the reader on a journey through the science and history of this amazing mineral.

      Just as in her previous books, Ms. Newman adopts a neutral and straightforward tone in her narrative. The explanations are clear, concise, and not overly technical. While the book covers a huge range of subjects, many of them quite complicated, Ms. Newman knows just how much space should be allotted to each and does not get bogged down in any one area. For instance, her survey of historical and present-day diamond sources is a terrific primer on the topic and gives up-to-date information about the various mining concerns and their output all over the world. This is a theme that could fill volumes, with the fine details of proprietorship, funding, and yield shifting constantly, but Ms. Newman handles everything in a very readable and uncomplicated way. I learned quite a bit that I did not know about historical diamond sources, such as Golconda, and much that I have missed out on about contemporary mines in far-flung locales.

     One excellent benefit of reading Diamonds cover-to-cover is all of the many questions it raises in the mind of the reader for later exploration. Whether you are most intrigued by ancient jewelry fashions or high-tech production of CVD gems, there is plenty of food for thought and an exhaustive bibliography to explore. Ms. Newman also cites the opinions and work of top experts in the field of gemology, as well as dealers and designers whose professions rely on diamond’s appeal. Many of these names will be familiar to NAJA’s membership, including diamond dealer Michael Goldstein, who weighs in on antique makes, and researcher Branko Deljanin, whose work on synthetic diamonds is cited.

     Reading Diamonds is a pleasure, but the photos and illustrations serve to perfectly enhance the text. In particular, Ms. Newman highlights early diamond cuts and jewelry, which are often overlooked in books devoted to more brilliant bling. Not every jewel depicted is beyond the reach of the average jewelry appraiser, either, and she makes a point of illustrating contemporary fashions from the likes of De Beers’ Lightbox. These pieces are budgetfriendly, utilize lab-grown diamonds, and are becoming increasingly more common in jewelry boxes around the world.

     Diamonds: Their History, Sources, Qualities, and Benefits is a beautiful book, both in its many photographs and illustrations and in its content. It gives the reader an excellent overview of the many facets of diamonds: historical, technical, industrial, decorative, and symbolic. The accessible text provides a bounty of information to the novice and fresh insights to the expert, all while working its nimble way from topic to topic. Renée Newman’s impressive body of work boasts a brand new star in this lovely book!
