Unusual locality example, these are glassy gemmy crystals of quartz forming a matrix less cluster and accented nicely with crystals of calcite. In excellent condition all around.The Ruschita metal mine, situated in the Rusca Montana basin of the Caras-Severin County in southwestern Romania, has a rich historical and geological background tied to polymetallic mineral extraction. Geologically, the area is characterized by complex metamorphic formations and intrusive contacts that produced significant skarn-hosted and hydrothermal ore bodies containing iron, lead, zinc, and uranium mineralization. Historically, while the district is globally celebrated for its ornamental marble quarries established in the 19th century, the separate metal mining operations targeted these complex sulfide and metal deposits to support regional industrial demands throughout the modern era.
