Chalcedony or Agate Mineral Specimen
The item is a small, irregular-shaped mineral specimen held in a hand for scale. It measures approximately 3-4 centimeters at its longest dimension. The specimen is primarily composed of a translucent, bulbous white material with a botryoidal or nodular formation. The surface is textured with small, individual spheres or grape-like clusters. Some areas of the white material have a slightly yellowish tinge. Attached to one end is a smaller section of a different material, translucent and greyish-purple or pinkish in color, also exhibiting a botryoidal structure, though with larger, more defined individual spheres. This greyish-purple portion also shows evidence of embedded sediment or small, light-colored crystalline fragments. There are visible deposits of a reddish-brown, earthy material in the crevices of both sections. The overall appearance is consistent with a type of chalcedony or agate, likely in its raw, unpolished state. No manufacturing details, maker's marks, or signatures are discernible. The condition appears as found, with natural inclusions and external sediment.
