This one is special. On the right side are numerous Strengite crystal groups to 2mm on golden yellow, fibrous Cacoxenite. I have not seen this combination before. Usually the Strengite sits directly upon the Kidwellite. The Kidwellite is a nice darker green and as usual has a globular habit. There is also excellent deep red and bladed Beraunite on the sides.

Eye-catching specimen. It is a thumnail sized specimen with an incredible nest of purple Strengite balls to 1mm sitting upon golden fibrous Cacoxenite with a little Kidwellite. Around the sides you can see a layer of dark red Beraunite.

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.
