YouTube Excerpt: The extraordinary 2.33-carat Winston Red Diamond has just been unveiled at the Smithsonian National Museum of Natural History (@SmithsonianNMNH)—marking a historic moment as the only Fancy red diamond currently available for public viewing. Known for their intense and highly sought-after pure red hue, Fancy red diamonds are among the rarest natural color diamonds in the world. According to the Gemological Institute of America (GIA)—a global authority in diamond grading and gemstone certification—only 0.04% of fancy color diamonds they evaluate are ever classified as Fancy red. The Winston Red is now recognized as the fifth-largest Fancy red diamond ever recorded. A team of expert researchers from @SmithsonianNMNH, @GIAgrams, and @Mines_Paris collaborated to conduct an in-depth analysis of this rare gemstone’s geological origin, color formation, and structural features. Their findings suggest the diamond likely originated from alluvial deposits in Venezuela or Brazil. Its vivid red color, one of the most prized in the colored diamond spectrum, results from a rare type of crystal lattice deformation caused by intense pressure and heat—similar to the process that gives rise to Fancy pink diamonds. The GIA Grading Report provides detailed insight into this remarkable diamond: Carat Weight: 2.33 carats Color Grade: Fancy Red (Natural Color) Clarity Grade: I2 (feather inclusions, girdle chips) Cut Style: Old Mine Brilliant Polish: Very Good Symmetry: Good Fluorescence: Faint Though it carries an I2 clarity rating, the Winston Red’s mesmerizing color and historical value far outweigh any internal inclusions. Gifted to the Smithsonian in 2023 by Ronald Winston, the gem is now part of a prestigious collection of natural fancy color diamonds, 40 of which are showcased in the world-renowned Winston Gallery—alongside iconic gems like the Hope Diamond. The Winston Red stands as a breathtaking reminder of Earth’s rarest geological marvels and is a must-see for anyone passionate about colored diamonds, gemology, and natural treasures.
