The Science Behind Fancy Color Diamonds | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on July 16, 2020.
Colored diamonds are priceless marvels of nature. From red and pink to green, blue, purple and brown, they exist in a rainbow of colors, caused by factors such as geologic forces, exposure to radioactive fluids or minerals, or atoms from trace elements being trapped in a diamond’s crystal lattice. Dazzled by these mysterious treasures? Join us as Dr. Sally Eaton-Magaña - Sr. Manager of Diamond Identification - explores the science of diamond color and how fancy color diamonds are created within the earth.

Is it from a scientific point of view possible that colored diamonds can change or fade in decades/ centuries of time? Because there are some stories from fancy colored experts that pink diamonds can go deeper in color over time? Like the moussaieff red diamond. It was a straight RED and became after new grading from gia a Purplish RED

Ok thank you...👍👌

minus 196 degree celcius into liquid nitrogen. Its hard to do in Singapore.

[@mourapj]

Thank you! Fantastic information. Just a question. Is it possible to change the word "defect" (negative connotation) to "characteristic" a more neutral word? Imagine selling a diamond and explain to the client that the reason for the magnificent color of the diamond is defects in their structure. Best regards.

[@kirkhammett231]

Uh... no.

[@robertthompson-nk3ip]

So I'm not sure what to do about getting a rough diamond authenticated or anything in the united states' I know it's extremely rare to find any but I did from all the test I learned to do online at home and purchasing a diamond tester everything says I'm on point the gravity test says density is 3.5 and I'm a poor man who doesn't have industry backing how can I get my stones checked out
