Botryoidal Chalcedony Specimen
This is a raw, unpolished specimen of Chalcedony, likely of the Botryoidal variety due to its grape-like or bubbly surface formation. The specimen is irregularly shaped and appears to be several inches in its longest dimension, based on the hand holding it in the image. The color is predominantly a translucent to semi-translucent milky white or pale grey with subtle hints of a very light blue-green in some areas. The surface exhibits a waxy to vitreous luster where the botryoidal formations are clearly visible. There are areas of natural matrix adhering to the specimen, which appear as rough, earthy material in shades of tan, brown, and off-white. Some fissures or natural cracks are visible within the crystalline structure, and there is surface dirt or staining in the crevices of the botryoidal formations and the matrix. The overall condition appears to be natural and unworked; there are no signs of cutting, polishing, or artificial enhancement. The form is organic and irregular, typical of mineral growth in vugs or cavities. There are no discernible maker's marks, signatures, or stamps, as this is a natural specimen. The age of such a mineral formation would be geological, likely thousands to millions of years old. The quality is that of a typical raw specimen, valued for its natural form and color.
