Description


ALEXANDRITE is known as emerald by day, ruby by night.

ALEZANDRITE is a beautiful rare stone and its magic of changing colours make it a must have for all stone lovers.  The very name of this gemstone brings to mind images of royalty.  It shows both red and green as pricipal colors, the principal colours of old Imperial Russia making it the national stone of Tsarist Russia.

The Russian created ALEXANDRITES are grown from chrysoberyl crystals and unlike lab corundum, these Czochralski Pulled ALEXANDRITES actually closely resemble the natural mined stones in many ways.  This lab created ALEXANDRITE is grown in a controlled environment to exhibit perfection.

ALEXANDRITE is a type of chrysoberyl, a rare oxide mineral and the hardest, most durable gemstones you can find.  ALEXANDRITE is scarce owing to its unique chemical composition as in addition to iron and titanium, it contains high quantities of chromium as an impurity, partially replacing aluminum.  Due to this impurity, spectacular green hues of this June gemstone can be seen.  Synthethic ALEXANDRITE makes this beautiful color changing gem available at a very affordable price.
