nm. alexandrite, type of stone used in jewelry

Discovered in 1830 in Russia, and named after Czar Alexander II of who was then Crown Prince of Russia, alexandrite is a form of the mineral chrysoberyl noted for its color change in different forms of light. In sunlight alexandrite looks blue-green, but in indoor (tungsten) light it the same stone changes to reddish-purple. Natural alexandrite with good color is very expensive today, as very little is still being mined, and there are many synthetics on the market. Synthetic color-change sapphire is also sometimes mistaken for alexandrite.
