  • Here is an old classic! This thick plate of layered rock has two superb topaz crystals on the top amongst many colourless quartz crystals. The topaz crystals are a very light yellowish colour which makes them easy to see amongst the quartz. Very nice!

  • A super-sharp, highly lustrous andorite crystal is exposed in an opening in this mostly cassiterite matrix. The andorite is nicely terminated. The cassiterite matrix is interesting in that it is sort of "honey-combed" and composed of thousands of tiny, almost acicular cassiterite crystals with a few tiny pyrite crystals. Very nice andorite specimen!

  • This is a Gorgeous mineral specimen!! Three, gemmy, ultra-lustrous cinnabar crystals are exposed but nicely protected in this deep, dolomite crystal-lined, gash in limestone matrix. The crystals are well formed and totally free of damage. The matrix is sawn on the bottom, back and one side as is commonly the case with specimens from this locality. You cannot tell from the display side. And it sits perfectly for display! Wonderful specimen of this mercury sulphide mineral.

  • A pristine, aesthetic cluster of quartz crystals graced by a sharp cubic crystal of pyrite at the front right. The pyrite is predominately cube with tiny octahedral modifications. The quartz crystals are clear and colourless with an extremely thin iron oxide coating that gives them a citrinous look. THIS is a nice specimen!!
Sphalerite, Chalcopyrite, DolomiteAAA CONNOISSEUR PAGES, Miscellaneous
  • Item #19986
  • Sphalerite, Chalcopyrite, Dolomite
  • 11.5x10.4x4.0 cm
  • Largest Crystal Size: 45mm
  • $260.00
  • 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!
