Rough Diamonds: Natural Crystal Shapes & Surface Features | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on January 21, 2021.

Once cut and polished, diamonds of similar size, shape and quality may look similar to the unaided eye. But in their rough form, natural diamonds have distinctive morphologies that tell much about their formation and their volcanic journey to Earth’s surface. Natural diamonds can form as glassy octahedral crystals, flat macles, in unusual spherical shapes and more. During their volcanic transit up to Earth’s surface, they also often acquire intricate markings from corrosive fluids. Tune in as GIA Research Scientist Dr. Evan Smith unravels the story behind rough diamonds’ unique morphologies.
