“Scalenohedral Calcite crystals with a very well marked and sharp interpenetration twin of two rhombohedrons streamlined by oriented micro-crystals of Hematite. The Calcite is implanted on a cavity of Quartz (amethyst) crystals with an intense luster and a deep color.Cantera La Bolsa, Paraje La Bolsa, Artigas, Uruguay.Found in 06/2009. Minor fluorescence long & short UV. ”
