A killer cabinet specimen with abundant, incredible sprays of Cacoxenite and purple spheroidal crystals of Strengite from 1 to 2.5mm. As is typical of this mineral assemblage the matrix is Beraunite which lines the out perimeter of the Cacoxenite.  A real nice specimen with Cacoxenite which glitters and pockets of purple Strengite. Eye-popping.
