Named after Alexander II, Czar of Russia, Alexandrite was discovered on his birthday in the early 1830’s. Because of this, it has been worn as an amulet of good fortune. Alexandrite changes color in different lighting. In daylight it is emerald-green, blue-green or pastel green. In incandescent light, it is violet, ruby red or purple. Its value is based on the limited quantity in which it is found, its size (rare over 2 carats), clarity and quality of color change. Alexandrite is recognized as one of June’s birthstones.
