Adularescence, the shimmering optical effect displayed by certain feldspar minerals, defines this gemstone’s key characteristic. This phenomenon arises from the layered structure of the mineral, causing light to scatter and create a play of iridescent colors, often resembling a rainbow or moonlight. A classic example is the blue sheen seen in many specimens.
Historically valued for its perceived mystical qualities and connection to lunar energy, this gem remains popular in jewelry and ornamental objects. Its delicate beauty and unique optical properties make it a sought-after material for artisans and collectors alike. This enduring appeal speaks to the inherent human fascination with natural wonders.
