Raw Agate or Chalcedony Specimen in Host Rock

This specimen appears to be a rough piece of agate or chalcedony in its natural host rock. The agate or chalcedony portion is translucent to opaque with a milky white and yellowish-orange coloration. It exhibits a botryoidal or bubbly formation on the surface, characteristic of chalcedony deposits. There are also some circular inclusion visible within the translucent material. The host rock surrounding the agate is a rough, greyish material with a granular texture, possibly basalt or andesite. The overall shape is irregular, reflecting its natural formation. There are no visible signs of polishing or cutting, indicating it is a raw, unworked specimen. The condition appears to be stable with no obvious breaks or extensive damage, although some wear on the host rock is expected. It is difficult to determine the exact age or provenance without further examination, but it is a geological formation.
