Kolenica

Kolenica is a small, smooth, round stone or mineral fragment that is typically found embedded within a larger rock or mineral deposit. These inclusions form naturally during the mineral's growth process when mineral-rich fluids deposit material inside a cavity or crack. Kolenica often has a distinctive appearance, contributing to the overall aesthetics and scientific study of minerals. They are valued by collectors and researchers alike for their unique formation and appearance, providing insights into geological conditions and processes that occurred during the mineral's development.
