  • A classic tuft of acicular pectolite crystals from the Jeffrey Mine. Just one of the forms that it has at that locality.

  • This is an odd one. The rounded crystal in the middle appears to be a chalcedony pseudomorph after calcite but it IS very fine-grained calcite. It is some sort of rounded crystal, complete with a trigonal pinacoid on the top. See photo. There are pure-white, elongated aragonaite crystals all around the calcite. There are also balls of spherical calcite on the specimen so, perhaps the original calcite crystal was overgrown with the finer-grained, almost botryoidal calcite? Whatever it is, it is cool! s

  • BC Mine
  • Black Lake
    Quebec, Canada
  • OK, this is not a world class aragonite specimen but it IS an interesting locality piece from this old, long-closed- asbestos mine in the Eastern Townships of Quebec. Looks like very elongated, white aragonite crystals formed in a seam in host rock. Different!

  • Item #26591

  • 9.5x9.0x12.0 cm
  • Largest Crystal Size: tr-55mm, Scol-14mm botryoids

  • British Canadian Mine
  • Black Lake
    Quebec, Canada
  • An opening at the front of this specimen is lined with pure-white botryoidal scolecite. Associated with the scolecite are tufts of extremely fine, fluffy tremolite. As well, there is coarser, acicular tremolite in the matrix of the specimen. Not from the Jeffrey Mine but another old asbestos mine not too far away, in southern Quebec.

  • The top of this matrix is carpeted with very light-green, terminated, prismatic diopside crystals, with a few orangey-pink grossular crystals scattered on the diopsides. Nice!

  • B.C. Mine
  • Black Lake

  • A mass of parallel, very light greenish, silky tremolite fibers from this long closed asbestos mine. Actually displays well for an unusual mineral like this.

  • An interesting combination. Much of the specimen is composed of waxy-green, pectolite crystals and on one side there are a number of tabular, colourless apophyllite crystals. Unusual!!
