Blue-green by daylight and purple-red by incandescent light, Alexandrite’s bewitching beauty fascinates us. Highly sought after, fine quality stones over three carats are increasingly rare. Alexandrite promotes emotional balance, creativity, and imagination. Because of its scarcity, especially in larger sizes, alexandrite is a relatively expensive member of the chrysoberyl family. It shares its status as a June birthstone with cultured pearl and moonstone.
Alexandrite is believed to bring good fortune to its owner and help enhance
self-esteem. It has been used for healing inner ear problems, clearing the lymph system, and for disorders related to the blood and circulatory system in general.
Alexandrite was originally discovered in Russia's Ural Mountains in the 1830s, it's now found in Sri Lanka, East Africa, and Brazil, but fine material is exceptionally rare and valuable.
Alexandrite, with its chameleon-like qualities, is a rare variety of the mineral chrysoberyl. Its color can be a lovely green in daylight or fluorescent light, changing to brownish or purplish red in the incandescent light from a lamp or candle flame. This is a result of the complex way the mineral absorbs light.
Alexandrite’s dramatic color change is sometimes described as “emerald by day, ruby by night.” Other gems also change color in response to a light-source change, but this gem’s transformation is so striking that the phenomenon itself is often called “the alexandrite effect.”
Alexandrite is also a strongly pleochroic gem, which means it can show different colors when viewed from different directions. Typically, its three pleochroic colors are green, orange, and purple-red. However, the striking color change doesn’t arise from the gem’s pleochroism, but rather from the mineral’s unusual light-absorbing properties.
Even in its rough form, this 70.94-carat alexandrite shows attractive color change.
