Globular light green Kidwellite on black, beady-looking and stalatitic Rockbridgeite(?). Amongst all of this are spherical groups of purple Strengite, much of which do not appear in the photos. Along the edges is a perimeter of deep red, bladed Beraunite (or Eleonorite).

Large specimen! The Kidwellite occurs as cloud-like formations, bubbly and globular in habit. It also shows colors of greens and yellows, which grades from a dark green on the left to a forrest green, light green and then a nice yellowish green and finally a flat out yellow near the center of the photo. On the far right side the Kidwellite covers bladed red Beraunite. The last photo shows the Beraunite.

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.
