This mystery rock was found with an embedded man-made like electrical component pin. It was found encased in a very hard dirt and only the tips of the pins exposed, and required many hours to clean around the pins using a dental tool. The material is solid, natural quartz and feldspar granite, has very little observed mica and not an accretion, concretion, or pumice. It does not contain any resins, cements, glues, limestone, mortar, or other non-granite binding agents. It is very hard, and estimated to be at least 100,000 years-old. What is its origin? What was its purpose?
