Alexandrite is the color change variety of the mineral chrysoberyl.  In incandescent or candlelight it turns to a purplish or brownish red color. In fluorescent or daylight it turns to a green or a blue-green color.  Due to this change poets have given it the description of "emerald by day and ruby by night".

Alexandrite received its name from Alexander II, Czar of Russia, because it has been said that Alexandrite was discovered in the Ural Mountains of Russia on his birthday in 1830.
