This calcite crystal is disposed very aerial on a matrix formed by quartz and numerous very brilliant pyrite and sphalerite crystals. The calcite crystal is doubly terminated and shows us the faces of the hexagonal prism along with those of the negative rhombohedron. Between transparent to translucent. It is worth highlighting the intense orange fluorescence and phosphorescence it presents under long-wave ultraviolet light.
