Fine Quality Alexandrite Diamonds - What You Should Know
Alexandrite is an extremely rare colour-change variety of Chrysoberyl. Originally discovered in 1830 in Russia’s Ural Mountains and named in honour of the future Tsar Alexander II.
Alexandrite has historically been one of the most sought after gems, and is very hard (Mohs hardness scale – 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 prices are determined by size, colour, clarity and the intensity of the colour change.
Fine quality Alexandrite reach amazing prices on the world market, and are very collectable. Purplish synthetic corundum (sapphire) is used to imitate Alexandrite; these are often brought back from Egypt and Africa, and sold in tourist shops around the world.
