Group of calcite crystals showing well defined edges and faces with rhombohedron and prism forms. Between translucent to transparent and disposed in a matrix of greenish-toned siderite. This specimen comes from col. Daunis. It is labeled as Somorrostro, but we think it can be associated with the mining zone associated to the Bilbao anticline, Gallarta-La Arboleda-Somorrostro. A Spanish classic.
