RM465   Calcite

La Araña quarry, La Cala, Málaga, Andalucía, Spain

Although our country is rich in different forms of calcite, we want to emphasize on this specimen that shows two generations of crystal growth. The first generation calcite clusters have a good size and orange to yellowish pastel tones. With an elongated striated prism and rhombohedral terminal top forms. They are translucent and brilliant, with echeloned growths on faces.
A second generation of small, but transparent and brilliant calcite crystals, is disposed near to perpendicular on the prism of the first generation. A colored and strongly fluorescent calcite from la Cala.


Size: 7,5 x 5,5 x 3,8 cm.
Main crystal: 2,5 x 1,1 cm.
