Pyroxmangite

Locality: Sunnyside mine, Silverton, San Juan Co., Colorado, United States
Formula: Mn²⁺SiO₃
Availability: Sold
Size: 4 x 4 x 3 cm - Miniature

Excellent specimen for micro mineralogy. The Pyroxmangite occurs as superb, pink, bladed crystals to 2mm. With it are exceptional crystals of green Sphalerite to 3mm. Amongst these crystals are white sprays of what I believe are Calcite clusters, brown rounded Rhodochrosite groups and waterclear Quartz crystals.

Tons of massive pink Pyroxmangite was once collected on the dumps. It was originally thought to be Rhodonite but later redefined as Pyroxmangite. Crystals such as these are rare from the Sunnyside. Given the quality of crystals on this specimen, it is doubtful it came from the dump. It was originally from the Fred Bird collection, which Hampson obtained.

The Sunnyside mine is one of Colorado's most famous, and infamous mines. In 1978, the upper workings directly below Lake Emma collapsed sending four million tons of mud through the mine. Fortunately the mine was idle that day and no one was killed. It took two years to clean out the muck.

Locality: Homestake mine, Creede, Mineral Co., Colorado, United States
Formula: SiO₂
Availability: Sold
Size: 10.5 x 7 x 5 cm - Cabinet

Nice cluster of frosted amethyst with crystals to 8mm. Hampson gives the locality as "Homestake mine" of the Creede district. I find no reports of a Homesake mine in Creede district. It is associated with platy Baryte on the backside, this may provide a clue to the localtiy.
