Alexandrite

Alexandrite is a rare Chrysoberyl variety that changes its color according to the light source: Emerald by day, Ruby by night. Abundant deposits were first discovered in Russia in 1830. The gem was named after the Czar Alexander II, and it caught the country's attention because its red and green colors reflected the Imperial Russian flag. Nowadays, Alexandrite is mostly found in Sri Lanka and Brazil. Because of its rarity and scarcity, especially in larger sizes, Alexandrite became one of the most expensive Chrysoberyl. The biggest Alexandrite already found to date weights 66 carats and it is displayed at the Smithsonian Institute, in Washington, DC, USA.
