COMMENTS :

No indications of heating, no indications of any other treatment
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.
