Botryoidal Chalcedony Nodule
The item appears to be an unpolished, natural chalcedony nodule. It exhibits botryoidal (grape-like) formations across its surface, with various lobes and protrusions. The color is primarily a translucent to semi-translucent light pinkish-tan, with areas of white and some darker brownish-orange inclusions or mineral staining. The surface texture is somewhat waxy or resinous, typical of chalcedony. There are visible areas of layered growth within the botryoidal structures. One area has a distinct inclusion which appears as a brighter white, seemingly crystalline formation within the translucent stone. There are no discernable maker's marks, stamps, or signatures, as this is a natural geological specimen. The estimated age is geological, formed over millions of years. Its quality is based on the clarity, color banding, and the completeness and aesthetic appeal of the botryoidal formations. There are no visible condition issues such as chips, cracks, or repairs, consistent with its natural state.
