Calcite from Washington Vein, Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b152a.JPG] Calcite from Washington Vein, Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b152b.JPG] Calcite from Washington Vein, Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b152c.JPG] Calcite from Washington Vein, Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b152d.JPG] Calcite from Washington Vein, Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b152e.JPG]

Calcite

Locality: Washington Vein, Sunnyside Mine, near Gladstone, San Juan County, Colorado

Specimen Size: 6.8 x 5.3 x 3.3 cm (small cabinet)


Unlike some of the other major mines of the San Juan Triangle (e.g., Camp Bird or Idarado), Calcite is not terribly common from the Sunnyside Mine. This piece features dozens of sharp, translucent, white scalenohedra of Calcite which are gently “dusted” with sparkling golden Pyrite in select areas. Great condition overall, and certainly hard to find from this particular locality. The Sunnyside Mine was one of the most prolific localities in the history of San Juan mining, producing over $150 Million in total metals over the course of its life. In addition to the tremendous amounts of Gold and other metals that came out of the Sunnyside, it provided collectors with some of the most distinctive and memorable display specimens from any locality in southwestern Colorado. This mine is probably best known for its amazing pink Rhodochrosite and green Fluorite associations, but the Sunnyside offered a lot more in the way of minerals.

Fluorite from Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b153a.JPG] Fluorite from Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b153b.JPG] Fluorite from Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b153c.JPG] Fluorite from Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b153d.JPG]

Fluorite

Locality: Sunnyside Mine, near Gladstone, San Juan County, Colorado

Specimen Size: 17.2 x 11.2 x 6.5 cm (large cabinet)
Largest Crystal: 9.7 cm on edge


This piece hosts one of the largest individual crystals of Fluorite that I have seen from the Sunnyside Mine! Typically the Fluorites from this locality show either octahedral, dodecahedral or even tetrahexahedral habits, but large cubes are not terribly common. This piece has a great mix of pastel lilac and charming emerald green hues in the translucent, sharp, well-formed crystals. The display side is in amazingly good condition, and as you can see from the photos, the piece is big, certainly bigger than the vast majority of Sunnyside Fluorite specimens ever found. The specimen is pure Fluorite, no matrix or associated minerals, and it really glows when backlit. The back left corner of the main crystal is NOT cleaved, but actually recrystallized, which is impressive for a piece of this size, as they are typically peppered with dings, cleaves and busted edges. This is an excellent opportunity to pick up a large cabinet display specimen of a colorful mineral from one of Colorado’s most classic localities (now defunct) for a price that will not break the bank. If you are a San Juan mineral collector, you’ll know that good specimens from the Sunnyside Mine are lacking on the market these days, especially large attractive Fluorite specimens like this one.

Rhodochrosite with Quartz “casts” after Anhydrite from Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b154a.JPG] Rhodochrosite with Quartz “casts” after Anhydrite from Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b154b.JPG] Rhodochrosite with Quartz “casts” after Anhydrite from Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b154c.JPG] Rhodochrosite with Quartz “casts” after Anhydrite from Sunnyside Mine, near Gladstone, San Juan County, Colorado [./colorado712/co712b154d.JPG]

Rhodochrosite with Quartz “casts” after Anhydrite

Locality: Sunnyside Mine, near Gladstone, San Juan County, Colorado

Specimen Size: 3.3 x 2.3 x 1.6 cm (miniature)
Largest Crystal: 1.6 cm


The Sunnyside Mine was one of the most prolific localities in the history of San Juan mining, producing over $150 Million in total metals over the course of its life. In addition to the tremendous amounts of Gold and other metals that came out of the Sunnyside, it provided collectors with some of the most distinctive and memorable display specimens from any locality in southwestern Colorado. This mine is probably best known for its amazing pink Rhodochrosite specimens, but it also produced some of the most distinctive “casts” from any ore body deposit in Colorado. This piece features several soft pink color rhombohedra of Rhodochrosite which are coated by a thin layer of crystalline Quartz. Additionally, the Quartz has formed somewhat blocky, sculptural, geometric hollow cavities or “casts” after preexisting Anhydrite. This phenomenon is seen throughout the Sunnyside Mine, and definitely looks even better when associated with Rhodochrosite.

Anhydrite (!) with Rhodochrosite and Quartz

Locality: F Level, Sunnyside mine, near Silverton, San Juan County, Colorado

Specimen Size: 3.5 x 2.7 x 1.6 cm (miniature)


ex.  Richard A. Kosnar


The Sunnyside Mine was one of the most prolific localities in the history of San Juan mining, producing over $150 Million in total metals over the course of its life. In addition to the tremendous amounts of Gold and other metals that came out of the Sunnyside, it provided collectors with some of the most distinctive and memorable display specimens from any locality in southwestern Colorado. This mine is probably best known for its amazing pink Rhodochrosite specimens, but it also produced some distinctive Quartz “casts” after Anhydrite. This piece actually FEATURES the elusive Anhydrite which, amazingly, was not dissolved away like the majority of the Anhydrite from this mine. This piece hosts several white/cream colored botryoidal aggregates of Anhydrite which are sitting on white Quartz matrix with accenting pink Rhodochrosite and minor sulfides. One of the very few pieces of this material that I have handled, and exceptionally rare on the market. This particular piece was mined in 1968 by Max Gallegos, was acquired by my father, Richard Kosnar, in the early 1990s, and later became part my collection. A great specimen of Anhydrite with most unusual form!

Quartz

Locality: Osceola Mine, Cunningham Gulch, Silverton, San Juan County, Colorado

Specimen Size: 10.7 x 5.7 x 4.6 cm (cabinet)


One of the very few Quartz specimens that I’ve had to offer from the Osceola Mine. This piece is a wonderfully crystallized “mound” consisting of sharp, prismatic, white, translucent Quartz crystals with a minor coating of an unknown mineral. I showed the piece to Robert Stoufer and he identified the locality for me. Very hard to find on the market, and more than suitable for any collector of Quartz specimens from Colorado, or just Colorado minerals in general.

Chalcopyrite with Quartz

Locality: near Silverton, San Juan County, Colorado

Specimen Size: 8.3 x 5.3 x 5.2 cm (small cabinet)


A good display specimen of Chalcopyrite coated by micro crystallized Quartz from San Juan County, Colorado. I obtained the piece from the Jaime Bird collection when it was distributed from the Arkenstone. It features several very sharp, well-formed, golden Chalcopyrite crystals with a notable patina which have a selective deposition of Quartz, exposing the Chalcopyrite crystals from a certain direction.

Quartz “casts” after Anhydrite on Quartz

Locality: Vein Outcrop, Dawn of Day (Sunshine) Mine, Cement Creek, Red Mountain District, San Juan County, Colorado

Specimen Size: 5.7 x 4.7 x 3.2 cm (small cabinet)


A beautiful small cabinet sized specimen from the famous Cement Creek area that produced some of the lesser known Quartz “casts” from the state. For years, people have written that these epimorphs were replacements of Quartz after Barite, and I always contested that this couldn’t be the case, and that the “casts” were most likely after Anhydrite. Finally, it appears that somebody else is on board with me as I read from Bill Dameron on mindat that “Dr. Virgil Lueth, New Mexico Tech, concludes from studies (as-yet unpublished paper 4/2011) that these and all San Juan quartz epimorphs apparently after barite are in fact after anhydrite”. This piece features a few epimorphs of “sugary” Quartz replacing Anhydrite with additional "sugary" Quartz crystals on massive Quartz matrix. Beautiful aesthetics and very eye-catching. Collected by Robert Stoufer in 2009.

Enargite

Locality: North Ore Body, Longfellow Mine, Red Mountain Pass, San Juan County, Colorado

Specimen Size: 3.8 x 2.9 x 0.9 cm (miniature)
Largest Crystal: 7 mm


Enargites from the famous Longfellow Mine are amongst the best in the state, and these pieces are incredibly difficult to find in good display specimens such as this. This particular piece is from my own personal collection, and actually once belonged to Warren Prosser, the noted author and geologist who worked in the San Juan Mountains of Colorado. The piece plays host to dozens of sharp, rather lustrous, attractive, metallic silvery-black crystals with no matrix. If you are a Colorado collector, don’t let this one pass by, as it is a good representation for the species from this noted Enargite producer.

Specimen Size: 5.8 x 4.2 x 3.3 cm (small cabinet)


ex.  Hal Miller


A very rich sample of the very rare lead antimony arsenic sulfosalt Guettardite from one of the few localities in the world for the material. This is one of only a few pieces of Guettardite that I have seen from the famous Brobdignag Mine which, in 1884, was actually the site of the first valid occurrence of Zinkenite, not only in Colorado, but the United States. See http://www.mindat.org/photo-253555.html for a similar specimen from the same mine. Very rare on the market, and this piece is the best that I have seen from this locality.

Barite

Locality: Bulldog Mine, 1 mile NW of Creede, Mineral County, Colorado

Specimen Size: 10.8 x 10.3 x 6.6 cm (cabinet)


ex.  Brian Kosnar


A beautiful and certainly eye-catching display specimen of Barite from the famous Bulldog Mine in Creede. This piece is loaded with dozens upon dozens of bright, sharp, highly lustrous, white to nearly colorless, tabular bladed Barite crystals forming beautiful "rosette"-shaped aggregates coating virtually all of the display side of the specimen. To top it off, nearly every crystal on this specimen is undamaged! The piece can be displayed from several angles, as you can see from the photos, and the quality of the crystals is as fine as anything I have seen from Creede. A superb cabinet sized display specimen from this important Silver mine in Colorado, and a more than worthwhile piece for any collector of Colorado minerals. From my own collection.

Aside from being a major Silver producing mine since the 1890’s, the Commodore Mine is well known for producing some excellent sulfide displays specimens, including some of the finest Sphalerites from Colorado, especially from the standpoint of gem quality Sphalerite! This piece is filled with highly lustrous, complex, modified crystals of green-honey-gold Sphalerite which are associated with a few soft golden color tetragonal crystals of Chalcopyrite. When backlit, some of the Sphalerites show great gemminess. A great cabinet size display specimen from this classic locality in southwestern Colorado.

Silver and Acanthite with Barite (polished slice)

Locality: Bulldog Mine, 1 mile NW of Creede, Mineral County, Colorado

Specimen Size: 15.0 x 9.8 x 3.5 cm (large cabinet)


ex.  Russ Honea


A great, large cabinet sized, polished slice from the famous Bulldog Mine in Creede featuring veins of Native Silver with grey Acanthite in white Barite matrix. Such a rich slab of the actual vein itself. This locality is best known for its glorious “sowbelly” slices of Amethyst / Agate / Chalcedony, which sometimes host Native Silver and Sphalerite. This piece is one of the very best slabs of Native Silver that I’ve seen from the Bulldog, and it would make a superb addition to any Colorado or native elements collection.

Quartz with several associated minerals

Locality: 210 Stope, 9360 Level, Bulldog Mine, 1 mile NW of Creede, Mineral County, Colorado

Specimen Size: 15.6 x 10.5 x 9.3 cm (large cabinet)


The Bulldog Mine operated from 1969 to 1985, producing 25 million ounces of Silver in that time = $675 Million in today’s market. My father acquired this piece directly from the miner who found it in 1979. It’s a strange piece for sure, unlike anything I’ve seen from this locality. The piece is filled with somewhat cavernous semi-brecciated vugs of crystallized Quartz and “Amethyst” along with Agate which are associated with bladed white Barite and micro minerals (possibly Pyrostilpnite and / or Xanthoconite). Additionally, the Quartz has an underlying pink hue that is caused by an unknown mineral (possibly Rhodochrosite?). The piece is more of a reference specimen, but if you collect Creede minerals, you can’t afford to miss out on this one, as it would make a unique addition to your collection.

Specimen Size: 8.2 x 6.7 x 3.7 cm (small cabinet)
Largest Hematite: 1.2 cm


ex.  Richard A. Kosnar


This is a great specimen from one of the most storied and well known districts in Colorado. The pegmatites near the Lake George area of Colorado have produced what most collectors and dealers consider to be the finest Amazonite specimens from the standpoint of superb color, top quality, wonderful display specimens and excellent associations. This particular specimen, has no Amazonite, but it is a great display piece  featuring a radial "spray" of sharp, semi lustrous, metallic grey pseudomorphs of Hematite after Siderite aesthetically perched atop a mound of white crystallized Microcline. To top it off, the base of the specimen shows a few pale lilac Fluorite crystals. The pseudomorphs are essentially undamaged, and are a perfect example of this well-known material. This specimen was collected over 30 years ago in August of 1980. Don't miss out on this great Colorado classic.

Topaz

Locality: Devils Head Area, Douglas County, Colorado

Specimen Size: 2.1 x 2.1 x 1.8 cm (thumbnail)


An excellent, GEM quality, sharp, lustrous, well-formed, classic colorless Topaz crystal from one of the most classic locales in Colorado for the species. One of the defining characteristics of  Devil’s Head Topaz crystals are small etching patterns on the termination, which can clearly be seen on this piece. A very similar specimen from the Denver Museum of Nature and Science (formerly the Denver Museum of Natural History) can be seen in “Minerals of Colorado” – 1997 in fig. 112. This is one of the best thumbnail gem Topaz crystals that I’ve had to offer from this locality, and is worth picking up if you are a thumbnail collector, a gem crystal collector, or if you collect Colorado minerals.
