Rough Agate or Chalcedony Specimen
This specimen appears to be a raw, unpolished piece of agate or chalcedony. It is irregular in shape, held in a human hand in the image, giving a sense of its approximate size, which is likely several inches long and a couple of inches wide. The material is predominantly translucent to opaque white, with areas exhibiting a waxy to vitreous luster. There are distinct areas of discoloration, appearing as earthy brown and reddish-brown stains and inclusions adhering to the surface and within fissures. Some areas show botryoidal or bubbly formations. Close examination reveals some internal layering, characteristic of agate, though the banding is not prominent or well-defined. There are no visible manufacturing details, maker's marks, or signatures. The piece exhibits a natural, unrefined state with no signs of cutting or polishing. The condition appears to be stable, with typical surface imperfections and natural wear expected of a raw mineral specimen. Its age is geological.
