🌎 Alexandrite is a rare mineral that changes color under different lighting—appearing green in daylight and red under incandescent light. This gemstone was first discovered in Russia’s Ural Mountains in 1830, and crystals large enough for jewelry are extremely scarce worldwide. ✨ #alexandrite⚡#minerals⚡#gemstones 👉subscribe Interesting Planet 👉more Channels
