Alexandrite is a rare and highly valued variety of chrysoberyl known for its remarkable color-changing properties. Under natural daylight, it exhibits a green to bluish-green hue, while under incandescent light, it shifts to a red or purplish-red color. This unique optical phenomenon, known as the "alexandrite effect," makes it one of the most sought-after gemstones among collectors and jewelers alike.
First discovered in the Ural Mountains of Russia in the 1830s, alexandrite was named in honor of Tsar Alexander II. Its discovery coincided with a period of Russian nationalism, as the gemstone’s red and green colors matched the imperial colors of Russia. Due to the depletion of the original deposits, high-quality alexandrite is now primarily sourced from Brazil, Sri Lanka, and East Africa.
