Alexandrite is a name with many meanings. It is a form of the mineral chrysoberyl that changes from green to red under artificial light. A man-made version of this mineral is sold in Mexico today. It changes from deep purple to aquamarine blue under artificial light. Alexandrite gets its name from Russian tsar Alexander II, who lived from 1818 to 1881, when the alexandrite crystals were first discovered in 1834. The Alexandrite listed here is glass made in the late nineteenth and twentieth centuries. Thomas Webb & Sons sold their transparent glass shaded from yellow to rose to blue under the name Alexandrite. Stevens and Williams had a cased Alexandrite of yellow, rose, and blue. A. Douglas Nash Corporation made an amethyst-colored Alexandrite. Several American glass companies of the 1920s made a glass that changed color under electric lights and this was also called Alexandrite.
