Winston’s Collection of Natural Color Diamonds Now on Display in D.C.
Ronald Winston, son of Harry Winston, donated the diamonds to the Smithsonian National Museum of Natural History in Washington, D.C.

The Winston Fancy Color Diamond Collection was unveiled Tuesday at the Smithsonian National Museum of Natural History in Washington, D.C.
The centerpiece of the collection is a diamond that is rare both because of its size and its color.
The 2.33-carat “Winston Red” is one of the largest red diamonds the Gemological Institute of America has ever graded as fancy red.
It is an old mine brilliant-cut diamond, which suggests it was cut before the mid-1900s.
“The red diamond is the highlight of my career, and I have never seen anything else like it,” Winston said in a press release when the museum announced the donation earlier this year.
“This donation to the museum represents my life’s achievements in this domain, and I am so happy to share this collection with the [Smithsonian] Institution and the museum’s visitors.”
Harry donated a historic blue diamond to the museum back in 1958 that is still on display there—the Hope Diamond.
The Smithsonian National Museum of Natural History is open seven days a week (except for Dec. 25) from 10:30 a.m. to 5 p.m. Admission is free.
More on the science and history of the “Winston Red” will be available in the spring 2025 issue of GIA’s quarterly journal, Gems & Gemology.
