Additional Info

Named after Czar Alexander II (1818–1881) Alexandrite is a rare and valuable color-change variety of chrysoberyl. Alexandrite possesses a surprising ability to change color - from green or bluish-green in daylight, it transforms to purplish or raspberry red in incandescent light.

Where to buy?
For Alexandrite check what Amazon has to offer. You'll usually find quite a selection from many different vendors. Worth a check. For other high quality gemstones (Rubies, Saphhires, Emeralds) and especially Diamonds, I highly recommend JamesAllen.
