DeYoung Red Diamond

The cause of the extremely rare deep red color of certain diamonds is not understood, but might be related to defects in the crystals' atomic structure. The DeYoung Red Diamond is one of the largest known natural fancy dark red diamonds. It is a modified round brilliant cut diamond that has a clarity grade of VS-2 and weighs 5.03 carats. The diamond was acquired by S. Sydney DeYoung, a Boston jeweler, as part of a collection of estate jewelry in which it was wrongly identified as a garnet. It was gifted to the National Gem Collection by Mr. DeYoung in 1987.
