Alexandrite is a high price stone most commonly set for jewelry as rings.
The alexandrite variety of chrysoberyl displays a color change dependent upon the nature of ambient lighting .
Color change phenomena
Alexandrite effect is the phenomena of an observed color change from greenish to reddish. With a change in source illumination. It results from small scale replacement of aluminum by chromium ions in the crystal structure. It causes intense absorption of light over a narrow range of wavelengths in the yellow region of the visible light spectrum.
Because human vision is most sensitive to green light and least sensitive to red light. It 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.
Stones from the Ural Mountains in Russia can be green by daylight and red by incandescent light. Other varieties may be yellowish or also pink in daylight and a columbine or raspberry red by incandescent light.
Stones that show a dramatic color change and strong colors are rare and sought-after. But stones that show less distinct colors may also be considered alexandrite by gem labs such as the Gemological Institute of America.
According to a popular but controversial story, The stone was discovered by the Finnish mineralogist Nils Gustaf Nordenskiöld (1792–1866). And named alexandrite in honor of the future Tsar Alexander II of Russia. Nordenskiöld’s initial discovery occurred as a result of an examination of a newly found mineral sample. He had received from Perovskii, which he identified as emerald at first. The first emerald mine opened in 1831.
5 carats stones and larger were traditionally thought to be found only in the Ural Mountains. But have since been found in larger sizes in Brazil. Other deposits are located in India, also Madagascar, Tanzania and Sri Lanka. Gemstones in sizes over three carats are very rare.
Today, several labs can produce synthetic lab-grown stones with the same chemical and physical properties as natural stone. Several methods can produce flux-grown, also Czocchralski (or pulled), and hydrothermally-produced stones. Flux-grown gems are fairly difficult to distinguish from natural gemstone as they contain inclusions that seem natural.
Czochralski or pulled alexandrite is easier to identify because it is very clean. And contains curved striations visible under magnification. Although the color change in pulled stones can be from blue to red. The color change does not truly resemble that of natural stone from any deposit. Hydrothermal lab-grown stones has identical physical and chemical properties to real stones.
Some gemstones falsely described as lab-grown synthetic alexandrite. They are actually synthetic color change corundum. Or also synthetic color change spinel. They are not actually chrysoberyl. As a result, they would be more accurate to describe it as a simulated alexandrite rather than synthetic.
This alexandrite-like sapphire material has been around for almost 100 years. It shows a characteristic purple colour change. It does not really look like alexandrite because there is never any green.
