Winston Red Diamond is 2.33 carat Fancy red Diamond. Formerly referred to as the “Raj Red,” the Winston Red is an old mine brilliant-cut diamond, Type IaAB (A) Group 1. It’s one of the largest of its kind ever found. (The Moussaieff Red Diamond is the largest in the public record at 5.11 carats.) The stone takes its name from Ronald Winston, who gave it to the Smithsonian’s National Museum of Natural History in 2023. The Winston Red is the largest red diamond going on public display. It will be featured alongside dozens of diamonds of many colors in a new ongoing exhibition, “The Winston Red Diamond and Winston Fancy Color Diamond Collection,” running indefinitely at the Natural History Museum’s Harry Winston Gallery.
