While the alexandrite was first discovered in the Ural Mountains of Russia in the 1800s, many of the finest examples of these stones have been found in Brazil. For example, the 17.08-carat stone known as the Whitney alexandrite can be found in the Smithsonian Museum of Natural History, having been gifted to the National Gem Collection by Carolyn Wright Whitney. Like the present stone, the Whitney alexandrite changes from bluish-green in daylight and fluorescent light to an intense purple in incandescent light. In terms of both rarity and originality, these Brazilian alexandrites outrank nearly every other gemstone known.
