Thumbnail, 2.0 x 2.0 x 1.9 cm
An unusual and unique thumbnail from the North Geronimo Mine of Arizona. Sparkly vanadinite microcrystals are richly dusted on two, sharp, gray calcite after fluorite crystals. This is an excellent and showy Arizona pseudomorph and combination specimen from a mine close to the famous and now-closed Red Cloud Mine. Ex. Sam Nasser TN Collection.
