Very characteristic translucent light toffee brown crystals of Fluorite on scalenohedral crystals of Calcite from Pint's Quarry, Raymond, Iowa, USA. Crystals of Fluorite measure to 1cm displaying lots of stepped growth and offsets. Associated with crystals of Calcite measuring to 2.8cm long, both the Fluorite and Calcite are spotted with spherulites of Marcasite. A well-formed crystal cluster of bladed Marcasite crystals sits towards one end of the specimen.
