  • 7.8x5.4x4.0 cm
  • Largest Crystal Size: 4mm
  • $55.00
  • Tsumeb

  • Namibia
  • A cluster of fairly sharp cuprite crystals is situated on the left side of this specimen on a bed of what I think are white dolomite crystals. There is one other cuprite crystal tucked away between some carbonate crystals. The cuprite crystals have tiny green crystals on them which I assume are malachite. Nice!
Cuprite, CalciteTsumeb Namibia, Assorted Minerals, Page Two
  • Item #14355
  • Cuprite, Calcite
  • 4.3x4.2x2.9 cm
  • Largest Crystal Size: 3mm
  • $60.00
  • Tsumeb

  • Namibia
  • The cavitiy on the top of this carbonate matrix is lined with a carbonate mineral that I'll call calcite. It is variously tinted by different oxides. Most interesting, though, are very sharp, dodecahedra of deep-red cuprite. These cuprite crystals have a small amount of tiny balls of malachite on them. Beautiful!
Conichalcite, MalachiteTsumeb Namibia, Assorted Minerals, Page Two
  • Item #17159

  • 8.5x6.0x4.3 cm
  • Largest Crystal Size: c-1mm botryoids
  • $65.00
  • Tsumeb
    Namibia
  • The top and front of this brecciated matrix is covered with malachite needles, which, in tur, has many lighter green botryoidal tufts of conichalcite on them. Nice example of this mineral that stands perfectly for display.

  • Item #17167
  • Malachite
  • 12.3x9.5x5.5 cm
  • Largest Crystal Size: 4mm
  • $60.00
  • Tsumeb
    Namibia
  • The top of this malachite-limonite-chalcocite matrix is covered with a druse of rounded aggregates of acicular malachite. The piece is significantly abraded but still looks great and should travel fairly well. Classic high grade ore!
Aragonate, var. TarnowitziteTsumeb Namibia, Assorted Minerals, Page Two
  • Item #19881
  • Aragonate, var. Tarnowitzite
  • 7.4x7.4x4.4 cm
  • Largest Crystal Size: 7mm
  • $80.00
  • Tsumeb
  • Otavi
    Namibia
  • This specimen is a plate of stout, well terminated aragonite crystals with a creamy-white colouration. Classic Tsumeb!
MottramiteTsumeb Namibia, Assorted Minerals, Page Two
  • Item #19886
  • Mottramite
  • 4.5x3.0x2.3 cm
  • Largest Crystal Size: n/a
  • $35.00
  • Tsumeb
  • Otavi
    Namibia
  • 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.
