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.
