Alexandrite-like refers to the ability of a gem material to change colors when viewed under different light sources such as daylight and incandescent lighting. It is named after the natural “change of color” gemstone alexandrite which is a variety of chrysoberyl. “Alexandrite-like” is most often used to describe a synthetic sapphire that changes from a reddish-purple to a blue color.
