History of Alexandrite dates back to Imperial Russia, where it was first discovered in emerald mines near the Tokovaya River in Russia’s Ural Mountains. Its Finnish discoverer initially mistook it for emerald before realizing it changed colors under different light sources. Often described as “emerald by day, ruby by night,” Alexandrite is a rare variety of the mineral chrysoberyl that changes color from bluish green in daylight to purplish red under incandescent light. According to legend, this gemstone was named for Alexander II because it was discovered on the future czar’s birthday in 1834. Because it’s so scarcely available, Alexandrite is practically unaffordable.In this ring you have Cats Eye Alexandrite even more rare stone!
