  • Schneckenstein
  • Kielberg, Vogtland, Saxony
  • 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 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!
Barite, CalciteAAA CONNOISSEUR PAGES, Miscellaneous
  • Item #19179
  • Barite, Calcite
  • 15.0x13.0x9.0 cm
  • Largest Crystal Size: 140mm
  • $1,750.00
  • Meikle Mine
  • Elko
    Nevada, USA
  • This is a world class specimen of barite! Several orangey-yellow barite crystals are aesthetically assembled on a bladed calcite crystal base. The crystals are thick-bladed and highly lustrous. The terminations are multiple terminations, as we often see with this group of minerals. The Meikle Mine is famous for large cavities(I'm talking 50-100 feet) lined with these types of calcite and occasional areas of excellent barite crystals, like this. Not a spec of damage! Difficult to find a better specimen!

  • Largest Crystal Size: as above
  • $1,500.00
  • Shikoku Island
  • IYO
  • A superb specimen of stibnite from the classic locality that has produced, arguably, the best specimens of this mineral. This specimen represents the best; long, smooth, highly lustrous, terminated crystal. Actually one smaller crystal attached to the larger. They don't come around like this very often!

  • $900.00
  • Mina San Jose
  • Oruro
  • 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!

  • Item #19969

  • 5.7x5.8x4.5 cm
  • Largest Crystal Size: 39mm

  • 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!

CinnabarAAA CONNOISSEUR PAGES, Miscellaneous
  • Item #19972
  • Cinnabar
  • 6.7x6.0x7.0 cm
  • Largest Crystal Size: 13mm
  • $350.00
  • Tongren
  • Tongren, Guizhou
  • 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
  • Item #19980
  • Pyrite, Quartz
  • 9.6x8.0x4.5 cm
  • Largest Crystal Size: p-21mm, q-40mm
  • $750.00
  • Spruce Claim

  • 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
  • $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!
PyriteAAA CONNOISSEUR PAGES, Miscellaneous
  • Item #19989
  • Pyrite
  • 12.2x8.0x6.0 cm
  • Largest Crystal Size: 44mm
  • $550.00
  • Ampliacion a Victoria Mine
  • Navajun, La Rioja
  • This is one of the most impressive single-cube pyrite specimens that I have ever seen! It shows a close-to-perfect cube of mirror-like-lustered pyrite perfectly exposed in matrix. This is the locality that produced the most perfect pyrite crystals in the world and this is a great example!!
