Alexandrite shares the honor of the June birthstone with pearls. It is one of the most widely know natural color shift stones in the world, and is also one of the most expensive gemstones you can buy, often fetching prices higher than that of diamond. Larger sizes are often difficult to come by and may not be available at all. Alexandrite will change its color from a reddish pink to a blue green depending on the type of light that hits the stone.
The stone was first discovered in the Ural mountains of Russia and more recently has also been discovered in Brazil.
Alexandrite is not treated and has a hardness of 8 - 8.5 making it a very good stone for everyday wear.
