Nice Natural Alexandrite Oval 8.94cts.

Medium green in daylight and medium light orangy red under incandescent light, the color change is strong and attractive. Although the clarity is not that good, alexandrites this large are extremely rare. An antique setting might be the best way to set this stone.
