Moonstone’s Famous Glow

Moonstone usually comes from the mineral adularia, named for an early mining site in Switzerland, Mt. Adular. Therefore, adularescence is the term coined for the stone’s ethereal moon-like glow. This phenomenon appears as a soft glow that floats beneath the surface of the polished gem. Imagine moon glow through a thin cloud cover.

Moonstone is made up of microscopic layer after layer of feldspar. Consequently, these bend and scatter light causing the ethereal glow of adularescence.

Roman historian Pliny wrote that moonstone’s shimmery appearance shifted with the phases of the moon. This belief was carried well into the 17th century. However, you can see the shimmer shift when the light around it moves, when the gem is moved, or if you move while viewing it.
