Piemontite is a rare, red epidote group silicate. This is a fine combination specimen from the famous No. 5 shaft at the Messina Mine of South Africa. Red piemontite microcrystals richly and preferentially cover three sides of a doubly terminated, sharply trigonal, transparent to translucent quartz crystal. Calcite crystals and kaolinite are additional, complimentary accessory minerals on the glassy quartz crystal. This is a fascinating doubly terminated quartz crystal, with one end being a sharp, single termination and the other end being multiply terminated. Ex. G.R. Glover Collection.
