  • Calcite
  • Calcite cm
  • Largest Crystal Size: 8.5mm
  • $85.00
  • Pugh Quarry
  • Custer
    Ohio, USA
  • This as an old USA classic! Years ago, calcite clusters like this were fairly common from the Pugh Quarry. We don't see them nearly as much any more. This is a striking large cabinet specimen showing a cluster of orangey calcite crystals on limestone matrix. Nice contrast! Slight terminal bruising on a couple of the crystals. Looks great.
Bornite, SlickensidesRocks and Ores, Sulphide Ores, Various Localities
  • Item #20993

  • 11.0x8.3x6.0 cm
  • Largest Crystal Size: n/a
  • $75.00
  • Junction Mine
  • Bisbee, Cochise Co.
    Arizona, USA
  • This specimen is rock, heavily laced trough with veinlets of bornite and disseminated bornite. It is not solid bornite but there is lots of bornite in it plus, I think a fair bit of chalcocite. The interesting thing is that on two sides, there are prominent slickensides that are composed of copper sulphides. Slick! (Pun intended).
TarbuttiteSecondary Minerals, Various Locations
  • Item #20990
  • Tarbuttite
  • 8.4x6.8x4.7 cm
  • Largest Crystal Size: 7mm

  • Skorpion Mine

  • Namibia
  • The top of this iron-gossan matrix is mostly covered with tarbuttite crystals. The crystals are not individual crystals but sort of composite crystals. The sub-crystals that make up the composite crystals have have sharp terminations and bevelled edges-faces. Some of the crystals are contacted from being in contact with the rock or minerals on the other side of the opening but many are excellent!

  • A rather delicious-looking, specimen of green smithsonite from this classic locality! The smithsonite is botryoidal with a very nice green colouration. It is a very showable specimen that is a cavity of smithsonite on a matrix of, I believe, mostly smithsonite and iron oxides.

  • $35.00

  • Here is an unusual one! This specimen is a cluster of white, well-shaped adularia crystals. Interestingly, it appears to have come from an "alpine cleft" type of environment because of the white asbestiform amphibole around the base. Very interesting and unusual!
