Gemological and spectroscopic properties of 43 CVD synthetic diamonds from Apollo Diamond Inc. were examined to characterize the latest generation of their CVD products. These samples, which included both faceted gems and partially polished crystals, were provided as representative examples of Apollo’s 2006–2007 production. Relative to the Apollo CVD products examined in 2003, the new samples showed significant improvements in size, color, and clarity. In addition to colorless and near-colorless material, fancy orange-to-pink colors are now produced. These high-quality CVD-grown diamonds, comparable in color and clarity to natural diamonds, can be identified using a combination of gemological and spectroscopic properties.
