Piemontite, Quartz, Calcite, Kaolinite from No. 5 shaft, Messina mine, Messina District, Limpopo Province, South Africa [db_pics/mdpics/MD-188378b.jpg]

7.1 x 3.0 x 2.6 cm. 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.

This fine specimen has crystals to 1.5 inches or 3.5 cm, and is nearly pristine. This is likely 100 years old and is a fine example of this classic calcite style from England. From an old private collection.
