Scientists have clarified how its color and internal structure formed, but its exact mine and early history remain unknown. The widely repeated $2.3 million figure is a secondary-media estimate—not a documented sale price or official appraisal.
What the Winston Red is
The Smithsonian National Museum of Natural History identifies the Winston Red as a 2.33-carat diamond with the Gemological Institute of America’s Fancy red color grade. The museum describes it as the fifth-largest known Fancy red diamond and the only Fancy red diamond on public exhibit in its 2025 study. Fancy red is exceptionally rare: the Smithsonian says fewer than one in 25 million diamonds are Fancy red, and that they make up 0.04% of fancy-color diamonds. Those figures use different denominators and should not be conflated.
Ronald Winston gifted the stone to the Smithsonian in 2023. The museum opened its Winston Red Diamond and Winston Fancy Color Diamond Collection exhibit on April 1, 2025. Sant Director Kirk Johnson called it “one of the most significant gifts ever received by the Smithsonian.”
Why the diamond is red
A 2025 study in the Gemological Institute of America’s Gems & Gemology examined the diamond using optical observation, spectroscopy, cathodoluminescence and photoluminescence. The authors classify it as type IaAB (<B), Group 1 “pink,” and describe both plastic deformation bands and networks of dislocations in its crystal structure.

The authors explain the stone’s pure crimson appearance as the result of a balance of absorption features, not one cause alone. These include a band at 550 nanometers associated with plastic deformation, as well as absorption involving nitrogen-related N3, H3 and H4 defects. The structural evidence indicates the diamond experienced substantial pressure and temperature conditions. The study’s conclusion is that “To achieve its red color and dense dislocation networks, the Winston Red diamond likely experienced immense strain under mantle conditions.”
This finding matters because it would be misleading to say the Winston Red’s color comes only from lattice distortion. The study describes deformation and defects working together; it does not establish that every red diamond has precisely the same features or history.

What is known about its past—and what remains a mystery
The earliest documented point in the diamond’s modern history is September 1938, when Jacques Cartier sold it to the Maharaja of Nawanagar. It was then known as the Raj Red. The gem’s old mine brilliant cut suggests it was fashioned before the modern round brilliant style, but neither its earlier acquisition nor the mine where it was found is known.
The GIA study considers Venezuela or Brazil plausible based on mineralogical characteristics and historical context. These are hypotheses, not confirmed origins. The researchers do not identify a specific mine or establish where the stone was before its 1938 sale.

Is the Winston Red really worth $2.3 million?
The $2.3 million amount should not be treated as an established value. IFLScience reported the approximate figure on June 6, 2025, based on an estimate of around $1 million per carat for comparable-quality stones. The Smithsonian’s collection materials and the GIA study do not state an appraisal or sale price. The figure is therefore a reported estimate, not evidence that the diamond sold for that amount or that it has an independently verified current market value.
Per-carat comparisons are especially limited for a museum-held stone with an unusually rare color and no disclosed transaction. They may provide context for a media estimate, but they do not establish what a buyer would pay for this particular diamond.
