G&G Features Pink Diamonds and Golden Pearls

The summer issue of Gems & Gemology includes a three-page foldout that illustrates the grading ranges for natural pink diamonds. The article, "Characterization and Grading of Natural-Color Pink Diamonds," was written by John King of the New York GIA Gem Trade Lab, along with a team of GIA researchers. With more fancy-color diamonds entering the mainstream, the article sheds light on the subtleties involved in color-grading not only pinks but all fancy-colored diamonds. The issue also has an update on the new enhancement of golden South Sea pearls. To order a copy of the Summer 2002 issue of Gems & Gemology or to subscribe, visit www.gia.edu/gandg or call (800) 421-7250, ext. 7142. The Summer 2002 issue of Gems & Gemology features a special foldout section on grading pink diamonds.
