The Gemological Institute of America has compiled its 30 years of synthetic-diamond research into a book, Gems & Gemology in Review: Synthetic Diamonds. The publication is the first in a projected series. The 300-page book, which features two full-size wall charts, was released at the 2005 BaselWorld trade fair in April. It includes material originally published in GIA's scientific journal Gems & Gemology. Topics include a historical overview of synthetic diamonds, from the time they were introduced by General Electric Co. in the mid-1950s to the most current information on high-pressure, high-temperature (HPHT) and chemical vapor deposition (CVD) synthetic diamonds. The book is available from GIA on its Web site, www.gia.edu.
