NCDIA, JVC Publish Color Diamonds Trade Guide

The Natural Color Diamond Association (NCDIA) and Jewelers Vigilance Committee (JVC) and have recently released “The Essential Guide to the U.S. Trade in Color Diamonds.” The Guide focuses exclusively on applicable regulations.

The Guide was developed in response to inquiries from the jewelry industry about the laws governing the manufacture, sales and marketing of color diamonds, JVC said in a release Monday. “Whether diamonds are colorless or color, commerce in diamonds continues to raise important concerns for the industry.”

The Guide includes an overview of the geology of natural color diamonds, simplified nomenclature to describe “natural, synthetic and simulated” and a description of the treatments used to alter color in diamonds.

It also includes guidelines to determine if information about diamond treatment to a diamond must be disclosed and answers frequently asked questions.

“Disciplined compliance with legal standards that govern the sales of color gemstones is necessary to maintain consumer trust in the diamond/gemstone industry and to protect the pre-eminent position of natural color diamonds,” NCDIA Executive Director Robert May said.

According to May, the law requires honest disclosure for all diamonds, adding that proper disclosure is imperative when a color diamond might be the result of a technological treatment.

 “The Essential Guide to the U.S. Trade in Color Diamonds,” is available online here, on JVC’s or NCDIA’s web sites.
