Sharp cubes up to 0.9 cm cover the face of this specimen. The crystals have a pale yellow color core with a thin purple internal phantom. This is a little unusual for the english fluorite that I typically see. (I did purchase it along with several other specimens from an English field collector). It is from Boltsburn Mine Flats, Rookhope, Durham Co., England.
This specimen is from Minerva #1 Mine, Hardin Co., Cave-In-Rock, Illinois. The witherite is well crystallized with a dull waxy lustre. The rather large grouping displays prominately against the grey matrix. A small transluscent fluorite sits perched on one side of the witherite grouping. Two older collection labels accompany our label.
Interesting specimen from Sweet Home Mine, Alma Mining District, Park Co., Colorado, USA. The large rhodocrosite showing on the bottom corner of this specimen is cleaved. However, there is a ribbon of lovely red rhodochrosite rhombs draped across the top of the matrix. Individual rhombs are up to 0.6 cm in length. The balance of matrix face has small quartz and pyrite crystals scattered across it.
The matrix of this specimen is a banded green malachite which is covered by a later generation of pale green chrysocolla. Lustrous dark green malachite crystals in turn spread across the contrasting chrysocolla. This specimen is from the Mashaba West Mine, Katanga (Shaba), Congo. I purchased it out of a private Canadain collection.
This specimen is from Denton Mine, Harris Creek District, Hardin Co., Illinois. Good specimens from this area have become hard to find. The main barite grouping is approximately 4.7 cm long and contrasts nicely with the faces of the purple fluorite cube they rest on.
