Moonstone is a type of feldspar mineral that radiates a unique effect known as adularescence – a swirling blue sheen that appears to pass through the surface of the gemstone as it catches the light. This pleasing sight display is mainly connected to the moonlight play on water, inducing a sense of mystery and enchantment. As a result, moonstone has been correlated with the feminine divine, lunar energies and the receding flow of emotions. Its association with the moon has led to the belief that it can enhance intuition and insight.
