SOLD Rhodochrosite with Quartz- cLassic
stock #SOLD AX-10-076
American Tunnel Mine, Silverton, San Juan Co.
Colorado, United States
7.4 x 5.1 x 3.1 CM (cabinet)
price: $0


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.

Dreamtime claim, Crystal Peak, Teller County
Colorado, United States
5.5 x 3.3 x 2.1 CM (small cabinet/large miniature)
price: $185
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.

Rhodochrosite -rare Colorado locale

3 x 2.8 x 1.5 CM (small miniature/ large thumbnail (toenail))

Spring update

A single rhomb crystal with fine deep red color from a 1960 find in Idaho Springs. Similar to the better know localities of Sweet Home (Alma) and American tunnel (Silverton this came from an unidentified mine (likely the Moose mine or any of several Central city sites). The collectors were the Hitchings (father and son team) on a family trip from Massachusetts to Colorado. They collected 7 specimens from a boulder in a dump, this being the largest rhomb. They were not sure of the mine name and recorded these only as Idaho Springs.

Colorado, United States
3.6 x 3 x .6 CM (miniature)

A simple single crystal of Barite with a dark phantom zone. This also has a druse of tiny sparkling Barites that add a little flash. In good condition and a nice example of the find.

Zircon- classic Colorado find
stock #15.1-703
North Cheyenne Canyon, El Paso County
Colorado, United States
3.4 x 2.6 x 2 CM (miniature)
price: $360
new june 17

A very sharp group of Zircon crystals with a great history. Collected in Cheyenne Canyon in 1945 by the late Warren Johansson in the last weeks before he was drafted. While awaiting his call up, Warren went on a series of legendary bucket list mineral hunting trips. He had been clued in by Clarence Coil that, long ago, some Zircons had been found in that area but the locale was lost. Warren located this spot and dug several nice pieces, some of the best ever found. This specimen was one of Warrens favorites and was pictured for his memoir. Warren passed in 2015 still active collecting in his 90s. This specimen is a fine Colorado classic from a great field collector.

Amazonite (Microcline) & Smoky Quartz
stock #15.1-300
Mona Mine, Pikes Peak, El Paso Co.
Colorado, United States
4.3 x 4.7 x 3.8 CM (miniature)
price: $440
Post Tucson 2015

Extra intense color for a Microcline, this miniature from Pikes Peak area, Colorado and has much deeper blue green color than most Colorado localities. In fine condition damage-wise, there is a nice association of Cleavelandite blades nestled between the crystals. An American classic locality, this is relatively recent find from a small working claim. Better in person, with great display impact in a small size.

Phenakite on Adularia
stock #AX-26-011
Mt. Antero, Chaffee Co.
Colorado, United States
3.4 x 2.5 x 1.7 CM (miniature)
price: $100
pre Tucson 2015 update

A nice, sizable Phenakite from Colorado. The old labels say Phenakite on Adularia, they are somewhat transparent and glassy. The main crystal is big for the locale at 1.1 CM, it has a fine glassy luster and is in good condition With magnification it seems to show some twinning and has unusually curved faces formed from several offset faces. A nice affordable Mt. Antero specimen.
