This exquisite 0.53-carat natural alexandrite showcases the gemstone's most prized characteristic—a stunning color-change phenomenon that shifts from lush green in daylight to deep red under incandescent light. Cut in a brilliant round faceted shape measuring 5mm, this VS-clarity stone displays only minimal inclusions invisible to the naked eye. Sourced from nature and completely unheated and untreated, it represents the pinnacle of alexandrite authenticity. A rare collector's piece for those who appreciate gemstones of genuine distinction and transformative beauty.
