Natural alexandrite is a very rare named variety of the mineral chrysoberyl. Small scale replacement in chrysoberyl of alumina by chromic oxide results in the formation of the variety alexandrite and is responsible for alexandrite's characteristic greenish to reddish color change.
Alexandrite cystals form in granitic pegmatites and mica schists.
Natural alexandrite gemstones are sawn, ground and polished from clear areas in transparent alexandrite crystals
