A very curious specimen of calcite with deformed and curved escalenohedron and rhombohedron faces. With some brilliance, yellowish color and translucent. Very aerial disposed on a matrix of dolomite peppered with pyrite.

A very aesthetic and huge size group of calcite crystals showing rhombohedral forms, elongated along the main axis. Good definition, yellow color, due to the iron oxide coating. From a Spanish classic locality.
