What is Adularescence?
Adularescence is special optical phenomena exhibited by Blue Moonstone. Blue Moonstone exhibits Blue schiller or adularia/ Blue Lustre. The schiller is produced because of light interference caused by the light having to weave its way through the layers with slightly different optical properties.

Cause of Adularescence in Blue Moonstone
Blue Moonstone is a gem from the feldspar group and is composed of layers of albite – potassium rich aluminium silicate and orthoclase – sodium rich aluminum silicate. The schiller is produced because of light interference caused by the light having to weave its way through the layers with slightly different optical properties. The adularescence is caused by scattered light passing through the exsolution lamellae that act as scattering centres, creating a bluish hue/ lustre.
