Quartz Rock Appraisal

Quartz Crystal Cluster on Matrix

The item is a small, irregular specimen composed primarily of a light tan to off-white matrix rock with several small, semi-transparent to opaque crystal formations embedded within and on its surface. The matrix appears to be a sandy or sedimentary rock, exhibiting a somewhat porous and textured surface. The overall dimensions are difficult to ascertain precisely without a scale, but it appears to be approximately 3-5 centimeters in its longest dimension, held comfortably between a person's thumb and forefinger. The crystals themselves are most likely quartz, given their common occurrence and visible characteristics. They are generally colorless to very light brown or gray, with some exhibiting a slightly milky or cloudy appearance, indicating either impurities or microcrystalline structure. Some crystal faces are moderately well-formed, showing typical hexagonal prism shapes, while others are more fractured or indistinctly terminated. A notable feature is the presence of several small, shiny metallic inclusions or mineral specks, potentially pyrite or another sulfide mineral, adding a subtle sparkle. The specimen shows natural raw edges, consistent with a mineral dug directly from the earth, rather than a polished or cut piece. There are no discernible man-made markings, signatures, or stamps. Its condition appears natural for a rough mineral specimen, with no visible damage from handling or processing, though some natural fracturing is present. The estimated age is geological, as are all natural mineral formations. This piece represents a natural mineral specimen, likely collected for its aesthetic appeal as a raw crystal formation.
