Smooth, rough-textured gray sphere

A spherical, gray rock dominates the image. Its surface presents a dichotomy of textures, appearing simultaneously smooth and polished in some areas while exhibiting roughness in others. The rock's size is substantial relative to the frame, and its form is largely uniform, lacking significant protrusions or indentations. The gray coloration is consistent across the visible surface. The object's function is not readily apparent, potentially serving decorative, geological study, or other purposes.
