Adularescence is a phenomenon observed in certain gemstones, particularly moonstone, where a soft, floating light appears to glow from within the stone. This effect is created by the scattering of light as it interacts with the internal structure of the mineral, specifically due to the presence of thin layers of different minerals within the stone. The most commonly recognized adularescent effect displays a bluish-white sheen that can appear to move as the stone is rotated in light.
