Unpolished Serpentine or Nephrite Jade Rough Stone
This specimen is a palm-sized, unpolished natural rock exhibiting characteristics common to the serpentine group or nephrite jade. The stone measures approximately 2 to 3 inches in length and features a waxy to greasy luster on its surface. Its primary coloration is a deep sage to forest green, punctuated by intricate, web-like white to light-grey veins and inclusions that suggest various mineral interactions during its geological formation. The physical structure is irregular and water-worn, showing smooth, rounded edges typical of river-bed or alluvial find, though the surface retains a matte, non-reflective finish indicating it has not been mechanically tumbled or polished. Notable features include a slightly translucent quality in thinner sections, particularly along the edges, and a dense, compact composition. There are visible surface scratches and minor pitting consistent with natural environmental erosion. The absence of specific maker's marks or signatures is expected for a raw geological specimen. This item represents a natural work of geological art, valued for its potential for lapidary work or as a tactile collector's specimen of metamorphic rock. Identification of the specific mineral variety would require further testing for hardness and specific gravity, but its visual properties strongly align with minerals found in serpentinite-heavy geological regions.
