GIA to unveil colored diamonds book at Symposium

The Gemological Institute of America will be releasing its new book, Gems & Gemology in Review: Colored Diamonds, at GIA’s fourth International Gemological Symposium. The event begins Sunday and runs till Tuesday and is being held in San Diego, Calif.

The book combines more than 70 years of articles and notes originally published in Gems & Gemology, GIA’s quarterly journal.

Copies of the book, edited by John M. King, will be available at Symposium in the G&G booth, located in the Elizabeth Foyer on the second level of the Manchester Grand Hyatt. Attendees will also have the opportunity to discuss colored diamonds with King during the “Meet the Authors” book-signing event Sunday and Monday from 12:30 p.m. to 2 p.m. in the Elizabeth Foyer.

With more than 100 entries, the book explores the characteristics, lore, and color grading of colored diamonds. In addition, it contains new introductory text and commentaries from diamond industry leaders. The 340-page volume also comes with a supplementary booklet of color reference charts. Several charts were created exclusively for this booklet.

King is technical director of the GIA Laboratory in New York and a respected authority on fancy-color diamonds. With more than 25 years of laboratory experience, he has written a number of landmark articles for Gems & Gemology and frequently lectures on colored diamonds and laboratory grading procedures.

Colored Diamonds is the second volume in the Gems & Gemology in Review series. Synthetic Diamonds, edited by GIA director of research James E. Shigley, was released in April 2005. Shigley will also participate at the “Meet the Authors” event.

Colored Diamonds is available for $59.95 plus shipping and handling. The color reference charts booklet can be purchased separately for $19.95. To order, visit or contact circulation coordinator Debbie Ortiz. at 800-421-7250, ext. 7142. Outside the U.S. and Canada, call 760-603-4000, ext. 7142.
