Alexandrite is the extremely rare colour change variety of Chrysoberyl.
Originally found in the Ural Mountains of Russia and named after Czar Alexander II.
Alexandrite has historically been one of the most sought after gems; it has a hardness of 8.5.
Greenish in daylight and purplish red to red in incandescent light the colour change is rarely seen in other gems apart from colour change Garnet and sometimes Sapphire. Alexandrite is now mined in Southern India, Sri Lanka, Madagascar and Brazil. The price is determined by size, colour, clarity and the intensity of the colour change. Fine quality Alexandrites reach amazing prices on the world market.
A purplish synthetic corundum (sapphire) is used to imitate Alexandrite and these were often bought back from Egypt and Africa by soldiers returning from war believing they had a natural Alexandrite. We have recently seen these synthetic stones for sale as Alexandrite in tourist shops overseas.
