Botryoidal Chalcedony Specimen
This is an untreated raw specimen of Botryoidal Chalcedony. The specimen is held in a hand, obscuring the full size, but it appears to be a hand-sized piece. The color is predominantly a translucent, milky white to pale yellowish-brown, with areas of opaque white banding. The surface exhibits a distinctive botryoidal texture, characterized by rounded, globular structures resembling bunches of grapes. Some areas show a crystalline or rough texture on the reverse or edges, suggesting it is fresh from a deposit. There are visible inclusions of a darker, possibly reddish-brown mineral, particularly in the rough areas. The luster appears waxy or vitreous in the botryoidal sections. No manufacturing marks, signatures, or specific age beyond its geological formation are discernible. The quality is assessed as good to very good for a natural specimen, showcasing the characteristic botryoidal formation clearly. There are no obvious signs of damage or repair apparent in the image, only natural variations and inclusions. The specimen presents a pleasing aesthetic typical of this mineral form.
