  • 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 dramatic cabinet specimen showing off sharp pseudomorphs of gmelinite after chabazite. The crystals retain their sharp rhombohedral form but the veneer of large gmelinite crystals belies the new mineral. Lustrous and a nice pink-orange colouration. Stands perfectly for display.

  • A spectacular plate, featuring feathery, elongated blades of lollingite and very sharp, black dodecahedra of lustrous magnetite. As well, there are a few, sharp, smaller arsenopyrite crystals and the white mineral appears to be aggregates of small, creamy-white dolomite crystals. This is a world-class lollingite specimen and a spectacular magnetite specimen. Displays extremely well!

  • 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!

  • An excellent and very interesting chalcopyrite crystal that is partially coated with tenorite and hematite. The crystals is very sharp and, as usual, twinned, showing nice stria and re-entrant angles delineating the twinning. I obtained this specimen in an exchange with the famous French collector, the late Alexandre Delerme, when he visited my home in 1997. Displays perfectly!

  • 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.
Pyrite, QuartzAAA CONNOISSEUR PAGES, Miscellaneous

  • Washington, USA
  • 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!
