Light purple gemmy prismatic lustrous crystals of creedite measuring to 1.4 cm in length coming off matrix. Some damage is present, the three prominent crystals are all in great condition. Displays nicely all around. The specimen comes with a previous label from the collection of Ray DeMark and dates to the 1980s.The El Potosi Mine, located in the historic Santa Eulalia District of Chihuahua, Mexico, is hosted within an extensive sequence of Cretaceous limestones that were intruded by Tertiary igneous rocks. This geological setting facilitated the formation of massive replacement ore bodies, including large mantos and vertical chimneys rich in lead, zinc, and silver. Discovered during the Spanish colonial era, the district underwent intensive large-scale commercial mining from the late 19th century onward. Beyond its industrial production, the mine became globally famous among mineral collectors for yielding world-class, pristine specimens of secondary minerals such as smithsonite, hemimorphite, gypsum, pyrrhotite and creedite from its deep oxidized zones.
