Kobyashevite over calcite with selenite needles from Oujela Mine of Mapimí, Durango, Mexico — This particular specimen was discovered in a cave in 1974. Due to the presence of stalagmites and stalactites, tiny crystals grew on top of the mineral giving its very fine, sparkling and "furry" appearance.
