Where Do Yellow Type Ib Diamonds Form in Nature? | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on December 10, 2020. Yellow diamonds with isolated nitrogen are rare and dazzling, accounting for less than 0.1% of natural diamonds. This is because, over time under high temperatures, the isolated nitrogen atoms that cause many of these diamonds’ intense yellow colors will aggregate and turn the diamonds pale yellow or near-colorless. What allows these rare yellow diamonds to retain their color? Tune in as GIA Research Scientist Dr. Karen V. Smit explores the atomic makeup and geologic journey of these stunning treasures.
