- Valenciana Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico
Excellent gemmy yellow-green hexagonal Milarite crystals intergrown with white adularia. The locals call this adularia Valencianite, as its luster and sharp rhombohedral form with a bit of a curve make it distinct from normal adularias crystals. The largest of the Milarites is .6 cm across and is classic for this well-known locality from old finds of the 1960s. Ex. Charlie Key.
