One Of The World’s Largest Fancy Red Diamonds To Be Unveiled By Smithsonian
The Smithsonian’s National Museum of Natural History has acquired the 2.33-carat “Winston Red Diamond,” one of the world’s largest fancy red diamonds. It will be unveiled to the public on April 1 2025 as part of the “Winston Fancy Color Diamond Collection,” a group of some of the rarest and most important gems in the world, the museum said.
The diamonds were gifted to the museum by Ronald Winston, the son of distinguished jeweler and gem collector Harry Winston. In 1958, Harry Winston donated the iconic Hope Diamond to the Smithsonian, laying the foundation for the museum’s National Gem Collection.
The Winston Red Diamond and Winston Fancy Color Diamond Collection will be featured in the museum’s Winston Gallery, offering visitors the opportunity to witness one of the finest collections of fancy color diamonds ever amassed, the museum said.
“This ranks among the most significant gifts ever received by the Smithsonian,” Kirk Johnson, the Sant director of the National Museum of Natural History. “The Winston diamonds are unprecedented in their beauty and rarity, and we are thrilled to welcome them as additions to our National Gem Collection.”
Natural red diamonds are among the rarest gemstones on Earth, according to the museum, and the “Winston Red Diamond stands out as exceptional.” At 2.33 carats, it ranks among the largest diamonds ever to have received the “Fancy red” color grade from the Gemological Institute of America (GIA). Researchers estimate that less than one in 25 million diamonds is a Fancy red, and the Winston Red Diamond is one of the most exquisite in existence.
