A great display of three classic minerals from the Pennine Orefield, at the Cambokeels Mine, Weardale. Platy pseudohexagonal crystals of Calcite mostly display on edge, formed on lustrous crystals of purple Fluorite measuring to 2.2cm. Drusy crystals of Quartz have developed on two faces of the Fluorite. An inter grown pyramidal colourless-white crystals of Quartz is the matrix. A fine combination specimen from the mine.
