Spectacular pyrite aggregate featuring numerous well-formed cubic crystals with classic striated faces and a bright metallic luster. The crystals display sharp terminations, silvery highlights, and a characteristic yellowish coating of limonite/goethite – typical for this famous Balkan locality. The piece has an excellent three-dimensional structure with crystals protruding in all directions, creating a very dynamic and display-worthy specimen. Perfect size for any collection – not too small, not oversized.
