June has three birthstones: Pearl (organic gem formed inside mollusks, symbolizing purity and wisdom), Alexandrite (rare chrysoberyl that changes color from green in daylight to red under incandescent light), and Moonstone (feldspar with a glowing adularescent sheen). Associated with Gemini and Cancer, all three connect to the Moon's energy. In Vedic astrology, Pearl (Moti) is the gemstone of the Moon.
