Glowing Diamonds | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on August 20, 2020. Glowing Diamonds: Fluorescence and Cathodoluminescence Imaging of Growth Structures and Defects Did you know that roughly 35% of diamonds fluoresce or glow under longwave UV light? Besides longwave UV radiation, other methods can be used to “excite” diamonds so that even diamonds classified as non-fluorescent will glow. These methods are important to scientists, because a diamond’s glow can reveal unique and colorful growth patterns that help scientists separate natural diamonds from those that are laboratory-grown. Join us as Sr. Manager of Diamond Research, Dr. Ulrika D’Haenens-Johansson, shines a spotlight on the importance of fluorescence and cathodoluminescence in diamond identification and research.
