Alexandrite

Alexandrite is the color-change variety of Chrysoberyl.  Named after Czar Alexander II, Alexandrite is one of the rarest gem materials on earth! The best quality alexandrite is forest green in natural day light and changes to blood red in incandescent light. To truly experience the color change of this gem you will need to view it in multiple light sources.
