A large plate of complex Fluorites crystals mixed with multiple minerals including Rhodochrosite Rhombs, Sphalerite, Quartz and misc Sulphides. The Fluorites are mostly a pale purple to almost colorless but a few smaller crystals have a distinct pink color caused by being formed on top of Rhodochrosite. Nearly all the crystals on this plate are lightly frosted and have a slightly "melted" look. This locality is located on the same mountain as the famed Sweet Home and Detroit City Mines. This locality is a small propect with minimal devolopment has been worked for specimens by a small crew for a few weeks each year. They choose to not name or provide exact location of the site to protect it. The Fluorites are clearly different in habit from most that come from the mountain and the overall esthetics of this piece are quite choice.
SOLD Covellite- Classic USA
stock #SOLD 16.1-531
Summitville District, Rio Grande County
5.8 x 4.2 x 2 CM (cabinet)
Bladed crystals of Covelite are clustered on edge in the classic form from Summitville, Colorad. On this piece the iridescent patina is similar to good specimens from Butte, but has the Colorado form. Crystals are distinct, well separated and sharp, this is nearly pure Covellite just a few tiny bits of adhering matrix. Covellite is a somewhat common mineral but almost always massive. Crystallized Covellite is quite rare as there were only three locations that ever were good sources, at those sites it was still rare. Now all those mines are long gone.
A super esthetic older piece from finds made more than 50 years ago (predating the famed Lees pocket). This is in flawless condition the cluster of Barites has fine steel blue color and contrasts with a yellowish Calcite matrix. In addition to the nice arrangement some of the Barite faces show a very unusual etching pattern seen in some photos here. Lots of visual impact for the size, the color is a bit richer than the more recent finds, all in all far better than "above average", an excellent old time Colorado specimen.
Topaz - Classic Colorado
Tarryall Mt, Park County
2.9 x 2.3 x 1.9 CM (thumbnail)
A very nice thumbnail with fine provenance. This was in the Warren Johansson Collection since September 1941, he obtained this from the legendary George M White. Warren was a student at that time and was very actively exchanging minerals while working on his Phd. George White is famed for his Topaz finds. This specimen has a flawless clear, undamaged Topaz crystal perched on contrasting matrix. A choice slice of mineral history.
Rhodochrosite with Quartz- cassic
American Tunnel Mine, Silverton, San Juan Co.
7.4 x 5.1 x 3.1 CM (cabinet)
Well defined and sharp rhombs of Rhodochrosite from the classic Colorado locale of the American Tunnel in Silverton. This is the "other" Colorado Rhodo locality that was world famed long before the great finds at Sweet Home. The Am Tunnel Rhodos are also not in the same high price bracket as Sweet Home, but can be quite choice. The locality had a long history of producing Rhodochrosite specimens usually a more pale pink or less well formed. This is a unusually attractive specimen with sharp red crystals that are well exposed and esthetic. Three dimensional, undamaged and far better than usual with a contrasting matrix. Ex collection of R and A Palmer, W Hladysz and A Dilldallion.
Fluorite on Smoky Quartz with Microcline
Dreamtime claim, Crystal Peak, Teller County
5.5 x 3.3 x 2.1 CM (small cabinet/large miniature)
Late Summer 2018
A classic Colorado pegmatite mineral from a relatively new find at the Dreamtime claim. Cubic deep purple Fluorites are perched on Smokey Quartz with some adhering Microcline. Esthetic presentation, this looks even better with backlight (we have not photographed this with backlight as that can be misleading). In person the Quartz is more transparent. A nice example of the Fluorites in this find very cool find.
