Alexandrite is one of the birthstones for June and has a unique color changing ability. The stone was first discovered in Russia in the 1830s by miners who mistook them for emeralds because of their deep blue-green hue. However, when they shined light on the stone and the colors changed to deep purples and reds, they knew they had discovered a new gemstone. They named the stone after Alexander II, the Tsar of Russia at the time of its discovery. Because it is a relatively new stone compared to many of the others on this list, it is not steeped in as much history and lore. However, Alexandrite is considered by many to be a good omen. Because of its color changing properties, for some it also represents the balance between the physical and spiritual.
Biography
The alexandrite variety displays a color change dependent upon the nature of ambient lighting called metamerism. Metamerism is the phenomenon of an observed color change from greenish to reddish with a change in source illumination. Alexandrite results from small scale replacement of aluminium by chromium ions in the crystal structure, which causes intense absorption of light over a narrow range of wavelengths in the yellow region (580 nm) of the visible light spectrum. Because human vision is most sensitive to green light and least sensitive to red light, alexandrite appears greenish in daylight where the full spectrum of visible light is present, and reddish in incandescent light which emits less green and blue spectrum. This color change is independent of any change of hue with viewing direction through the crystal that would arise from pleochroism. It is a form of chrysoberyl. Pari passu, alexandrite is considered to be the national gem of Russia in honor of Alexander II Romanov.
