Alexandrite is the birthstone for June together with pearl and moonstone.

•         It forms orthorhombic crystals. This stone was first discovered in the Ural Mountains in Russia on the day of birth of the Tsar of Russia, Alexander. So they named the stone after him. This is a rare stone. It is almost always cut up as gemstones. Because of it's rarity it is one of the most expensive of the Gem stones.

•         The colour is caused by chrome. In Alexandrite the colour is so balanced that it is seen as green in normal daylight. The wavelength of a normal indoor bulb differs, it is incandescent light. Under this light the stone appears as red.

•         Synthetic corundum's treated to react like Alexandrite can also have a colour changing ability. Only buy from a reputable dealer.
