A dramatic and showy specimen of very highly lustrous brassy pyritohedrons to 2.2 cm sprinkled with small sphalerite crystals from Huanzala, Peru. This beautiful piece is undamaged and was photographed with two different lighting systems to show the intense lustre. 8.7 x 8.3 x 4.9 cm
13.0 x 8.6 x 5.8 cm. Lustrous, jet-black sphalerite crystals, some twinned, form a fine and very rich cabinet zinc ore specimen from the well-known Wudong Mine of China. This lead-zinc mine is much better known as the source of the rhodochrosites currently coming from China. There is rhodochrosite on the back, which confirms the source. Ore are specimens very rare from this locality. Ex. Wes Parker Collection.
7.3 x 6.5 x 4 cm. An outstanding pair of large (up to 3.5 cm) very dark and highly lustrous twinned Sphalerites. Combined with the distinctive long and slender Quartz crystals, this makes a wonderful combination. Very aesthetic. Ex. Martin Lewadny Collection.
A beautiful, showy and pristine specimen of super-brilliant brassy and striated pyritohedrons with sphalerite crystal clusters scattered on the pyrite faces from the famous and now-closed Gilman District of Colorado. 5.3 x 3.4 x 2.6 cm
A SUPERB and AESTHETIC Elmwood Mine specimen of a highly lustrous, translucent and etched purple fluorite cube with excellent edge phantoms and topped with two pointy "ears" of highly lustrous ruby-jack sphalerite crystals and a shock of sparkly dolomite crystals! Elmwood specimens of this quality are rapidly disappearing, due to the recent closing of the mine. 4.2 x 4.2 x 3.6 cm
13.7 x 8.9 x 7.0 cm. A huge specimen of galena matrix covered with gemmy, pastel-green crystals of fluorite. The fluorite crystals are to 2 inches, 5 cm. They are very transparent, deeply gemmy so that you can see into them to the matrix an inch or so underneath. The coverage is all around the specimen, 360-degrees, up and over all sides. A beautiful accent of jet-black sphalerite crystals hangs on one side. Weighs 1.5 kilograms. A major example from the 2006 finds here.
4.8 x 4.4 x 3.5 cm. A strikingly sharp, lustrous, jet-black sphalerite crystal from the Picher Field of the Tri-State District. This superb, large single crystal aesthetically rests on a shard of pastel-pink dolomite crystals. Complete-all-around, the frontal view is pristine. This is classic, old-time material from Oklahoma and the noted George Feist Collection # 2897. Outstanding for the species and locality.
4.4 x 3.7 x 2.7 cm. Classic, old-time, highly desirable material from the famous Picos de Europa Mountains of Spain. A striking cluster of sharp, lustrous, gem, orange-red sphalerite crystals in complex, sub-parallel formation. The transparency and color of the sphalerite is exceptional. See the article in the Mineralogical Record, May-June, 1996: Famous Mineral Localities: The Picos de Europa Lead-Zinc Deposits, Spain.
4.7 x 3.8 x 2.9 cm. A classic and desirable Creede Sphalerite specimen. The crystals themselves are very gemmy with the typical honey and green color that one is accustomed to seeing from this mine, and they are associated with minor Chalcopyrite and Galena. The largest Sphalerite crystal measures 1.3 cm across. You do not see these specimens any more, and they are simply some of the most classic pieces from any ore body in Colorado. From the Emerious vein. Ex. Richard A. Kosnar Collection.
4.4 x 3.6 x 2.2 cm. Colorado collectors will tell you that obtaining specimens from Gilpin County is very difficult because the vast majority of the mining took place before WWII and good quality pieces simply are not around. The Patch Mine near Central City in Colorado is one of the most classic localities on the front range. Gilpin County is the site of the first discovery of Gold in Colorado, and the Patch Mine (often referred to as the Glory Hole Mine) is a still standing landmark just southwest of Central City. This piece is filled with classic, sharp, lustrous, water-clear, colorless scepter Quartz crystals associated with black tetrahedral Sphalerite crystals on massive Quartz matrix. The largest Quartz crystal measures 1.0 cm long. A fine specimen of this material. Ex. Brian Kosnar Collection.
21.3 x 18.2 x 10.9 cm. A large (9.7 cm on edge) and highly dramatic lilac colored cube of fluorite sits atop a crystallized mound of reddish-brown sphalerite from the Elmwood mine in Tennessee. The fluorite itself is amazingly sharp, with good gemminess and light color zoning (ranging between lilac and colorless), but it's the incredible size and quality of the piece that makes it so significant. The secondary cube on the side of the specimen is a nice accent to this attractive large cabinet specimen. This piece is close to 30 years old, and is a significant US fluorite, especially coming from this prominent and celebrated zinc ore body.
3.5 x 3.0 x 1.3 cm. A classic and seldom seen matrix specimen of Rhodochrosite from the famous Brooklyn Mine in the San Juan Mountains of southwestern Colorado. This piece features a few bright pink, sharp, somewhat lustrous, rhombohedral crystals of Rhodochrosite on crystallized sphalerite. Ex. Richard Kosnar Collection.
8.2 x 4.6 x 2.8 cm. A stunning, water-clear, sharply terminated quartz "obelisk" is beautifully accented with an interesting protruding wreath of sparkly, brass-yellow pyrite microcrystals over sphalerite from the Panasqueira Mine of Portugal. The quartz is complete-all-around, nearly pristine. Classic and superlative combination material from this famed locale.
14.6 x 10.5 x 6.7 cm. Classic baryte "balls" to 5.8 cm with clusters of lustrous, ruby-jack sphalerite are dramatically set on the two-sided, wedge of sparkly, drusy quartz-covered limestone matrix on this very impressive cabinet specimen from the less common and now-closed Cumberland Mine of Tennessee. The Cumberland is very near to the Elmwood Mine and was not known as a great specimen producer. Baryte and quartz are rare from the Cumberland, so this is an exceptional combination specimen from this locale. Ex. Walt Gaylord Collection: mine geologist for the Elmwood and Cumberland Mines. His note indicates that the piece was collected in 1994 from O6S #4 within the mine.
Better in person - an aesthetically stunning Peruvian combo piece, with sharp, super-lustrous, large striated crystals of sphalerite accented with balls of snowy calcite along the bottom and a bit of pyrite. Contact around the periphery where removed from matrix. 5.1 x 4.0 x 2.3 cm
