natural fissure in gemstone
Adularescence is caused by the diffraction of light as it hits thin, alternating layers of orthoclase and albite within the gem. This produces the appearance of a floating, cloud-like, blue to white light inside the gem. A blue sheen is produced if the albite crystals are very fine.
