Rhodochrosite -rare Colorado locale
stock #17.1-868
Idaho Springs, Clear Creek County
Colorado, United States
3 x 2.8 x 1.5 CM (small miniature/ large thumbnail (toenail))
price: $390
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.

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 Cleavlandite 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 #ALEC-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 unusualy curved faces formed from several offset faces. A nice affordable Mt. Antero specimen.
Actinolite pseudo after Diopside (Uralite)
stock #8.AE-736
Calumet Mine, Turret District, Chaffee County
Colorado, United States
8.8 x 5.2 x 5.5 CM (cabinet)
price: $240
pre Tucson 2015 update

A very well documented and fine Colorado classic piece, this comes with 5 old labels, one of which notes: Collected in 1946 by C.G. Coil. Clarence Coil was a significant figure in Colorado Mineralogy. Well formed, terminated crystals are on several sides and in one large vug. This was in many collections over the years, including Elberto Tealdi (Milan, Italy) and Richard Kosnar. The esthetics and satiny luster in person show why it was included in these fine collections.
Rhodochrosite with minor Sphalerite, Pyrite, Quartz
stock #A7-548
Sweet Home Mine, Alma
Colorado, United States
2.6 x 1.7 x 1.1 CM (thumbnail)
price: $330


A well composed Rhodo thumbnail with great color from the Larry White collection. The piece is mostly just 3 rhombs juxtaposed with almost no matrix. Good translucency and luster this is a nice yet affordable example. The cost of any good Sweet Home specimens has consistently gone up every year, and since "they ain't makin 'em no more" the supply is now very small.
SOLD Sylvanite
stock #SOLD ALEC-10-102
Cripple Creek District
Colorado, United States
6.75 x 4.9 x 4 CM (cabinet)
price: $0


A very well crystallized example of this Gold Telluride, from the Ruth and Andy Palmer collection. Older material, this specimen dates before 1940. The matrix also contains micro crystals of other un-identified tellurides, but the main event here is the 4.5 CM large zone of crystallized Sylvanites. The largest of these reaches 1.5 CM most are 1 CM or less. A sharp and distinct specimen in excellent condition.
