Apatite on Pyrite
Huanzala Mine, Huallanca District, Dos de Mayo Province, Huánuco Department, Peru
12.3 X 12.5 X 9.5cm
By far the best Apatite I've ever seen from Huanzala, with a lustrous, pale greenish blue crystal measuring 2.1cm across the face, capping the terminated end of a bipyramidal Pyrite in a nest of numerous other bipyramidal Pyrites. The photos speak for themselves, I think, and the piece comes with a custom-made lucite base. There is minor chatter and pealing on the upper right-hand side of the crystal as shown, and a scattered bit of chipping in the Pyrite. Regardless, this piece is world-class at every level, even showing a bit of banding from the sides revealing a very faint central zone of pinkish purple, not visible when looked at down the c-axis. Numerous hexagonal outlines of "starter-growth" crystals are visible on the pinacoidal termination, as are a few very fine, discontinuous vertical striations that may be vestiges of an early attempt to clean the face. #EG-001 $3,500

Carrollite in Calcite with Spherocobaltite and Chalcopyrite with Bornite
Kamoya South II Mine, Kambove District, Katanga Copper Crescent, Katanga, Democratic Republic of Congo
Unique matrix-piece featuring a mirror-bright Carrollite measuring 3.0cm across majestically capping a cleaved edge of a terminated Calcite crystal. The white Calcite has inclusions of partially crystalline Chalcopyrite with purplish gray Bornite, and small bits of the Carrollite and the entire terminated face of Calcite are dusted with micro-spheres of reddish pink Spherocobaltite! This specimen captures an unparalleled story of the paragenesis of this small, defunct, world's-best locality, which shows latest movement that locally dislocated the Carrollites. On the back of the main crystal is such a zone, slightly rough and overgrown with a small dusting of Chalcopyrite, which surived the "rubbing-alcohol" test that would have shown if these had been attached with an epoxy. I acquired this nearly a decade ago when a geologist who had worked in the DRC brought them to the room I was working in Denver. There were maybe 20 -30 specimens total, including this one, and none had been cleaned. The Carrollite is so bright I had to avoid too much reflected light in the photographs! #EG-005 $12,500
Elite Specimens I
White Caps Mine, Manhattan District, Toquima Range, Nye County, Nevada, USA
8.5 X 8.5 X 5.5cm
A Stibnite explosion radiates from a scrap of jasperoid matrix in this cluster of characteristic "chisel-tipped" crystals from pre-World War II, as the Government issued the US War Production Board Limitation Order L-208 in 1942 to shut down all "non-strategic" mines in the USA, including gold mines like White Caps in Nevada. The luster is best described as reflective on the sides of the crystals, and "soft" on the tips, which comprise myriad minute terminatons. Good specimens from White Caps are difficult to find, but a great specimen with rich provenance is nearly impossible to come by. This piece resided in the Crystal Bar Collection in Virginia City for some time during its 1860s - past operations, possibly as a trade from a miner to a bartender for a splash or two? As the Crystal Bar was transitioned into a Welcome Center for the tourist crowds that visit Virginia City each year, the collection was sold off and this piece was acquired by well-known mineral dealer Scott Kleine (Great Basin Minerals). I acquired this nearly a decade ago from Scott, through a three-way deal involving the late collector Dr. Raul Madrid. In excellent condition, save a few crystals sheared near their bases, normal for anything of this age!
Barite on Calcite
Bush Pocket (aka Batch Plant Pocket), 1075’ Level, Meikle Mine, Lynn District, Elko County, Nevada, USA
12.0 X 11.0 X 8.5cm
Glassy, gemmy, and truly "golden" Barite from one of the four major pockets encountered at Meikle, this probably came out between 1995 and 1997. This piece was instantly recognized as significant, and was photographed for the seminal article for Mineralogical Record published in 1999; see the image in the bottom right-hand corner, from the Min Rec article and showing this masterpiece in the center. The "Crown-Jewel" is a glowing, 7.5cm-wide, doubly terminated crystal with no damage. Comes with a custom lucite base. Enough said...
Apatite with Fluorite and Chalcopyrite
Akchatau Mine, Akchatau, Karagandy Province, Kazakhstan
21.0 X 10.0 X 4.5cm
Glassy, gemmy blue Apatite crystals to 1.4cm clustered amongst numerous dark purple, bipyramidal Fluorites, all dusted by a latest generation of grape-jelly purple microfluorite preferentially coating faces of earler Fluorite and partially coating the Apatites. From the famed singular find, Collector / Dealer / Show Promoter Martin Zinn originally presented the entirety of this unique occurrence of 25 - 30 specimens in his showroom at Tucson in the late 1990s. I've spoken with Mr. Zinn twice about the specimens and this particular piece. This is one of the three largest pieces from the find, and almost all of the pieces now reside in museums. One of maybe three or four left for the public, this specimen provides a possibly once-in-a-lifetime opportunity to personally acquire one of these rarities! Comes with a customized lucite base, and could trim into two or maybe three smaller pieces...
