"The Essential Guide to the U.S. Trade in Color Diamonds" gives detailed information on treatments and treatment disclosure.

New York--The Jewelers Vigilance Committee (JVC) and the Natural Color Diamond Association (NCDIA) have released "The Essential Guide to the U.S. Trade in Color Diamonds," the associations announced this week.

The NCDIA and the JVC developed the book in response to inquiries from the industry about the laws governing the manufacture, sales and marketing of colored diamonds.

The guide includes an overview of the geology of natural-color diamonds, simplified nomenclature to describe "natural," "synthetic" and "simulated," and a description of treatments used to alter the color of the stones. It also includes guidelines on when diamond treatments must be disclosed and answers to frequently asked questions regarding colored diamonds.

Cecilia L. Gardner, JVC's president, CEO and general counsel, said of the guide, "Natural color diamonds are very rare...and very expensive. Consequently, these diamonds are often imitated so manufacturers will likely continue to develop new technologies to create synthetic and imitations. The guide details various treatment procedures and explains the information that jewelers need to disclose if a diamond has been treated, if the treatment is not permanent, if the diamond requires special care or if the treatment significantly affects the value of the gemstone."

Robert May, NCDIA executive director, said legal compliance is necessary to maintain consumer trust in the diamond industry and to protect the pre-eminent position of natural-color diamonds.

"The law requires honest and timely disclosure for all diamonds. Legal compliance and proper disclosure is imperative when a color diamond might be the result of geological processes that began millions of years ago, or the consequences of a technological treatment that began this morning. The guide is a simple-to-understand, essential tool for sales associates or anyone communicating with consumers about color diamonds," May said.
