Alexandrite is a natural gemstone that falls under the chrysoberyl mineral group. Alexandrite was discovered in Russia, and it’s named after Czar Alexander II, who ruled from 1855-1881. This gemstone occurs naturally when traces of chromium alter the coloration of its crystals over time due to natural radiation.
