Girasol Opal Quartz Appraisal

Rough White Girasol Opal Quartz (Moon Quartz)

This item is a rough, unpolished specimen of Girasol, a variety of quartz also known as Moon Quartz or Milky Quartz. It exhibits a distinct translucent-to-opaque milky white color with a soft, misty appearance that is characteristic of this silicate mineral. The physical construction is rugged and irregular, featuring sharp, angular edges and a prominent conchoidal fracture pattern on its surface, which is typical of high-silica stones when they are broken or chipped. The specimen appears to be approximately one to two inches in length, though its exact dimensions are difficult to confirm without a scale. Notably, it displays a subtle inner luminescence, a quality known as ‘girasol effect,’ which allows light to seemingly glow from within rather than just reflecting off the surface. There are no visible maker's marks or signatures, as it is a raw geological specimen. The condition is consistent with 'rough' material; it shows natural pitting, jagged ridges, and a matte texture where it hasn't been smoothed by water or industrial polishing. Because it is a natural stone, it represents a geological formation rather than a specific manufacturing period. The craftsmanship is nonexistent as this is a natural formation, but its quality is indicated by the consistent saturation of white color and the lack of visible dark inclusions or matrix rock attached to the specimen.
