Microfeatures of Gems: Geologic Implications | GIA Knowledge Sessions Webinar Series

Inclusions are more than imperfections or clarity characteristics. They can teach us much about gemstones’ journeys and reveal otherwise inaccessible information about Earth’s formation. What stories do diamond inclusions tell about Earth’s mantle? What do rutile needles and three-phase inclusions teach us about corundum and emerald, respectively?
