Another fabulous video from GIA.

Dr. Evan Smith, Ph.D., GIA research scientist, has dedicated his work to methodically characterizing the inclusions found in rare diamonds. In this video presentation recorded at the 2017 JCK Las Vegas show, Smith shares his findings on the unexpected origins of big diamonds and what their characteristics tell us about the earth.

“Next time you look at a diamond, I hope you see it not only as a beautiful, valuable piece of gemstone; [you should also know that] diamonds are some of the most scientifically valuable samples of our earth,” Smith said. In this video, he explains that as diamonds form more than 100 miles below the earth’s surface, they often trap mineral inclusions that reveal the chemistry of the earth’s mantle.
