Following the success of two previous editions, this informative guide to diamonds returns in a completely revised, updated and expanded edition. Clearly written, and presented in a redesigned format, the book provides the reader with essential information on diamonds and the diamond industry and the tools for recognizing and assessing a diamond's chief properties. This edition is richly illustrated throughout in full colour, with images of some of the world's most beautiful diamonds as well as illustrations of the different types of cut and shape used in the diamond trade. The reader will also find useful grading scales for cut and clarity, a chart of carat weights and corresponding sizes, examples of diamond grading reports, and a directory of international institutes and gem laboratories. The new chapter on natural colour diamonds provides information and illustrations for each main colour group, making this one of the few books in the field to offer a basic guide to this expanding and increasingly popular sector of the diamond industry. Newly added text on the origins of diamonds and the early days of the diamond trade, and on the recent developments of inscriptions and branding, add further value to this information-packed book. A final chapter on the life story of one very special diamond, from its discovery to finished jewel, is vividly told through images and text. The popular first edition was praised by readers for its clarity, comprehensiveness and usefulness as a practical guide. This new edition will be of interest both to those already familiar with the book and to newcomers, whether professional jewellers and gemmologists, students and teachers of gemmology, prospective buyers of diamonds, or simply those interested in learning more about this most prized and captivating of gems.
