Alexandrite
Alexandrite is a variety of mineral
chrysoberyl, the color-change variety. In incandescent or
(spotlight) it turns to a brownish red color. In fluorescent or
(daylight) it turns to a green blue-green color. Due to this
change poets have given it the description of “emerald by day
and ruby by night”. Alexandrite received it name from Alexander
II, Czar of Russia because it has been said it was on his
birthday in 1830 that Alexandrite was discovered, in the Ural
Mountains of Russia.
