Tsumeb, Namibia, Calcite

Calcite is not a rare mineral in the world. Well crystallized specimens are not all that common, though! Calcite occurred in beautiful specimens from Tsumeb, as an accessory mineral. Here are some very nice reasonably priced examples.

  • Sharp, white hexagonal aragonite crystals are present in a recess in this matrix. The crystals are all stubby, hexagonal prisms with sharp, hexagonal pyramidal terminations. An index card from the old collection indicates that it was acquired in Johannesburg in 1976. Classic!

  • A clean specimen of off-white, sort of shaggy calcite scalenohedra. The crystals are lustrous with coherent crystal faces near the middle of the crystals tending to more multiple terminations closer to the actual terminations of the crystals. Old Thames Valley Minerals label accompanies the specimen. Shows well!

  • This is an odd one. The top of the piece is mostly calcite crystals that grade from brownish to colourless. They are mostly covering a botryoidal white mineral, with pearly lustre, that I believe is willemite. As well, there are small hexagonal willemite crystals around the edges. Lightly fluorescent.

  • OK, you pseudomorph collectors. This matrix has a number of pseudos that appear to be pink calcite crystals after a larger bladed mineral. Just quartz crystals, iron oxide and calcite crystals elsewhere on the siliceous matrix. Interesting and attractive.
