  • $350.00
  • Joplin
    Missouri, USA
  • THIS is an interesting specimen! It shows two large, complex sphalerite crystals that are partially covered with 2-4mm, golden tetrahedral crystals of chalcopyrite. Of note, though, is that the chalcopyrite is oriented or epitactixially oriented on the sphalerite, so that the chalcopyrite crystals all flash at the same time because they are all oriented in the same way. I've tried to show this in one of the photos. The matrix is a thin plate of cherty limestone with the two large crystals on it and smaller sphalerite, chalcopyrite and dolomite crystals in between and around. Attractive and excellent specimen!

  • An interesting specimen composed of interweaving tubular aggregates of mottramite. I think it has a grey coating of another mineral since it has that colour on the outside and the more normal look of mottramite on the interior of the tubes. Tiny calcite or smithsonite rhombs on the mottramite. EDS confirmed.

  • Here is a pretty one! Both sides of this plate are largely covered with sharp, emerald-green dioptase crystals and tiny, sharp, brown crystals of bayldonite. The bayldonite crystals are curved microcrystals that are confirmed by EDS analysis. The colour of the dioptade crystals in the photo's is not accurate. They are a more "blue-green" that is typical of dioptase. I could just NOT reproduce the colour accurately, this time. Beautiful!
