Colorless Diamonds | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on April 29, 2021.
Colorless natural diamonds or “white” diamonds are admired all over the world for their brilliance and fire and treasured as symbols of romance. But did you know that most colorless diamonds aren’t actually colorless? Many contain subtle hints of yellow, brown or gray. In this webinar, we’ll discuss the causes of color for diamonds on the D-to-Z scale, trends seen in their quality characteristics, and how these diamonds are distinguished. Prepare for a brilliant journey with Dr. Sally Magaña, Senior Manager of Diamond Identification, as she dives into the science of one of the world’s most popular gems.

Hi how are you? May i know is diamond an electricity conductor?

[@Pr1ckles]

Only Type IIb ie the blue ones coloured by Boron, the electric conductivity test is therefore diagnostic when testing colourless diamonds (care: the only other material which is electrically conductive is synthetic moissanite)
