About Alexandrite Gemstone
Alexandrite is a rare variety of chrysoberyl best known for its remarkable color-change effect — appearing green to bluish-green in daylight and shifting to red or purplish-red under incandescent light, a phenomenon caused by trace chromium interacting with different light sources. First discovered in Russia's Ural Mountains in the 1830s and named for Tsar Alexander II, fine alexandrite is now also found in Brazil, Sri Lanka and East Africa, though genuine stones with strong color change remain scarce at any size. At 8.5 on the Mohs scale, it's durable enough for regular wear while remaining one of the most collectible gemstones in the world. Because color-change quality varies so widely from stone to stone, an independent lab certificate is essential when buying alexandrite — every stone in Jamsora's collection is graded and certified to confirm it's natural before it reaches you.
