Heulandite from Rat's Nest Claim, Custer Co., Idaho, USA [db_pics/pics/ST884a.jpg] Heulandite from Rat's Nest Claim, Custer Co., Idaho, USA [db_pics/pics/ST884b.jpg] Heulandite from Rat's Nest Claim, Custer Co., Idaho, USA [db_pics/pics/ST884c.jpg] Heulandite from Rat's Nest Claim, Custer Co., Idaho, USA [db_pics/pics/ST884d.jpg]

Pink Heulandite on white Mordenite from the recent (approx. 20 year old) Rat's Nest claim in Idaho. This is a particularly aesthetic example from this find, which has produced oustanding (best ever?) North American Heulandite. Individual crystals reach 3.5cm and are undamaged. Ex. Lanny Ream.

Brassy, metallic Chalcopyrite crystals on translucent Siderite crystals from a limited find at the Kaiwu Mine in China. These were a one time find back in 2012 or 2013 and make stunning specimens due to the contrast in color and form between the Chalcopyrite and Siderite. The Chalcopyrite is bright and metallic with a slightly reddish irridescent surface coloration. The Siderite are translucent brown and lenticular in habit. There are also small white Dolomite crystals in areas. Fifteen cm! This is a large, museum sized specimen, which was unusual for the find, that is amazingly free of any damage (most were smaller and had some damage). This association hasn't been found since.


ST941 - Azurite $ 2800
Shilu Mine, Yangchun Co., Yangjiang Prefecture, Guangdong Province, China
cabinet - 11.5 x 7.5 x 6.5 cm

Large, intergrown rosettes of Azurite crystals from early production at the Shilu Mine in China. This is an old Al Ordway specimen and comes with his old label. Al was one of most famous California field collectors and a really fine mineral dealer. A complete all around undamaged floater with no points of attachment. Most of this find were singles with subpar luster and some damage. This is a very 3-dimensional piece composed of multiple intergrown rosettes. Better in person!

Glassy apple-green crystals of Apophyllite in an absurdly aesthetic bow-tie cluster.  This specimen is the epitome of natural art.  The cluster of Apophyllite crystals are perched dramatically atop peach colored Stilbite crystals. In the world of Apophyllite specimens, one in thousand is a bow-tie formation. Of those few, 99 percent have damage of some kind. Do the math, this is a special and rare specimen. Comes with a custom Lucite display stand.

Yorkshire, England [db_pics/pics/ST939h.jpg]

Complete crystal group of the rare mineral Volkovskite from the Boulby Mine in England. This is one of only two known terminated crystal groups collected from a single find made deep in a section of the mine that extends out under the Altlantic ocean. The Volkovskite was found during normal mining operations for potash when the mine machinery stalled when it encountered a mass of the much harder Volkovskite. Because Volkovskite damages mine machinery, the area where it was found is now avoided and it is unclear if anymore will be recovered. This recent find of Volkovskite has set the world standard for the species and this specimen is one of the best. The specimen has crystallized surfaces all around - most were just cleavages (the cleavage structure can be seen on the bottom of this specimen, last photo).


ST945 - Benitoite with Neptunite $ 18000
Gem Mine, San Benito Co., California, USA

Stunning and important Benitoite/Neptunite specimen from the Gem Mine in California. This specimen is composed of a flat schist matrix partially covered by white Natrolite hosting two large Benitoite, Neptunite, and a single Joaquinite crystal. The largest Benitoite is 3cm wide (and the second crystal is not much smaller). The truely great Gem Mine specimens are composed of Benitoite, Neptunite, and Joaquinite on white Natrolite - this specimen checks all the boxes. This visually appealling specimen was in the personal collection of the late California mineral dealer Al McGuinness. Al was an active dealer in California during the heyday of Benitoite mining and had the opportunity to select the best. The fact that he kept this particular specimen speaks to it's exceptional quality and visual appeal. 


ST946 - Dioptase $ 12000

Large, lustrous Dioptase crystals on white Calcite from Tsumeb, Namibia. The Dioptase crystals reach 2.3cm in size and are translucent to transparent.  Although Dioptase specimens are found at other worldwide localities, those from Tsumeb, especially on white Calcite crystals, are considered the world's best and let's face it, Tsumeb is the magic word to most connoisseurs of fine mineral specimens. The Dioptase crystals show a unique fine etching that extends into the gemmy crystals. Dioptase is notoriously difficult to photograph and this is MUCH better in person. At 12cm wide, this is a large and significant Tsumeb Dioptase.
