CVD Landscape
Fluorescence is an integral part of diamond analysis that displays varying growth defects. Each color provides visual clues to the growth chemistries and defects formed. Gemologists use this data along with other spectroscopic features to determine a diamond’s origin and treatment history. The fluorescence features in this experimental CVD block grown by GIA (figure 1) are reminiscent of a landscape with trees reflecting into a lake during a sunset (figure 2, illuminated using a DiamondView equipped with a UV light).
CVD diamond technologies have improved vastly over the last decade. Researchers at GIA grew this CVD block over several growth runs to gain a better understanding of CVD diamonds. This block captures the essence of nature within a laboratory setting.
