A Brief History of Alexandrite

There are a small number of talismanic stones which have gained their reputation in our time. Alexandrite is one. It is a variety of chrysoberyl that was found in Russia, associated with the emerald mines on the Takowaya, in the Ural region. The discovery of alexandrite is claimed to have been made in 1831, on the very day Alexander II (the heir-apparent) reached adulthood. It was named alexandrite, in his honor, by Nordenskjold, the mineralogist. Alexandrite in gem form rarely weighs over one to three carats. It is characterized by pleochroism of a fine green changing to a bright raspberry red.

In Ceylon larger gems have been found, occasionally weighing 60 carats each. This is rare. Usually the gems weigh one or two carats. The color of these alexandrites is darker green, and the change in incandescent is not as profound as the Russian stones. Red and green are the Russian national colors, making alexandrite a great favorite in Russia. It is looked upon as a stone of good omen and fortune in that country. Russian alexandrite has not been mined in decades. The majority of alexandrite available on the market today originated from Brazil, and occasionally India and Madagascar. Alexandrites from these localities exhibit an impressive color change from a bluish-green to a bright raspberry red.
