Looking more like modern art than a rock – this is a dramatic specimen of big, sharp, intergrown tetrahedrite crystals with gunmetal luster, measuring to over 3 cm. Nice! 10 x 6 x 2.3 cm
A wonderful specimen distinguished not only by the huge, sharp tetrahedrites (to 2 cm on edge), but also by a coating of chalcopyrite that gives them a most unusual luster and color. 9.1 x 6.4 x 4.3 cm
Well, after many good years as one of the top stars in the mineral world, these beautiful rhodos from the Sweet Home seem to be running out. Because of the clearly dwindling supply, there are rumours of the mining coming to an end . They get more expensive every year, what is left from the miners. So if there was ever a time to get one, this might be it. This is a large and showy specimen that features dozens of gemmy pink-red rhombs to about 0.8 cm, interspersed with small quartz needles and tetrahedrite. It is not a major rhodo per se, in that the crystals are small, but it IS a super display piece with lots of color and crystals of very high quality overall, whose richness and quantity add appeal. 13 x 10 x 1.5 cm
3.8 x 3.4 x 2.3 cm. A classic, old-time combination specimen from Cornwall, England. Lustrous, brassy, lightly iridescent chalcopyrite crystals to 1.1 cm with textbook, tetragonal form are richly and nicely scattered on the quartz matrix with charcoal-gray tetrahedrite crystals. Certainly over 100 years old in this quality. These are really sharp chalcopyrite crystals for Cornwall.
7.1 x 5.5 x 3.2 cm. This piece features several sharp, lustrous, metallic grey/silver color tetrahedral crystals of Tetrahedrite measuring up to 2.7 cm on edge. They are associated with some very gemmy, stubby, colorless Quartz prisms. There is one spot on this specimen where the Quartz crystals have formed a beautiful "flower"-like or "star-shaped burst" which is sitting atop complimenting Tetrahedrite crystals in a similar shape. Ex. Brian Kosnar Collection.
Very pretty, bright pink isolated crystals of rhodochrosite intermixed with tetrahedrites (including a fine one of 1.8 cm), bright pyrites and small, snowy quartz crystals – all on a crystal of milky quartz. A Peruvian combo specimen that has it all! 7.5 x 3 x 3 cm
From the new find during recent mining activity in 2003, this piece features the largest crystals (2.3 cm across) yet to be seen from the find. It has a group of sharp, highly lustrous "stepped" tertrahedra aesthetically sitting atop Quartz and associated with Pyrite octahedra. Please note that these crystals are very difficult to photograph and look much better in person. There were very few of these found and I''m told that the mine has already stopped producing specimens of this material. 4.7 x 3 x 2.9 cm
6.7 x 6.5 x 2.8 cm. Splendent, brilliant black to silvery-black tetrahedrite crystals to 1.3 cm richly and showingly cover the massive sulfide matrix on this excellent speicimen from the well-known Mercedes Mine of Peru. The crystals are simple tetrahedrons and have striated faces. Highly representative material of the species and locale.
12.6 x 10.3 x 4.7 cm. Richard Kosnar mined the Sweet Home for a few years during the late 1970's and managed to collect some excellent Rhodochrosite specimens. This piece is from one of the last pockets that Rich opened before he was done at the mine. The Rhodochrosite crystals on this specimen have nice pink-red color with decent gemminess. The largest Rhodochrosite measures 1.1 cm across. They are sitting atop a mix of black, lustrous Tetrahedrite and Quartz crystal matrix with minor associated Pyrite. Ex. Richard Kosnar Collection.
3.4 x 3.2 x 3.0 cm. A large, sharp and lustrous, battleship-gray tetrahedrite crystal nicely accented with a lustrous, brass-yellow pyritohedron on one face from the long-extinct Daly-Judge Mine of Utah. Two of the three faces are well-crystallized, with the third, out of sight face being contacted. A large, seldom available tetrahedrite crystal from this old-time, well-known locale. Ex. Ydren Collection.
6.5 x 6.4 x 3.4 cm. An old-time, very rich and fine tetrahedrite specimen from the historic Tintic District of Utah. Lustrous, lightly iridescent, brassy, tetrahedral tetrahedrite crystals cover two sides of the drusy quartz covered sulfide matrix. Ex. Sunshine Acres School and N.A. Wintringham Collection. Classic and rarely available material from this venerable locale and probably dates to prior to World War I.
20.3 x 15.4 x 4.7 cm. Richard Kosnar mined the Sweet Home for a few years during the late 1970's and managed to collect some excellent Rhodochrosite specimens. This piece is from one of the last pockets that Rich opened before he was done at the mine. The Rhodochrosite crystals on this specimen have nice pink-red color with good gemminess and sharp faces. The largest Rhodochrosite measures 1.0 cm across. They are sitting atop a mix of black, lustrous Tetrahedrite and Quartz crystal matrix with minor associated Pyrite. This mine is now completely defunct, and will never produce these world class quality Rhodochrosite specimens again.
8.2 x 6.4 x 4.7 cm. A large, very rich specimen of sharp, modified Tetrahedrite crystals from Peru. These crystals, often intergrown or sprinkled with showy brassy Chalcopyrite, measure to .9 cm along the edge. The Tetrahedrites have superb luster and have fascinating modifications on the faces and edges. All rest on massive Sphalerite, and there are several large, intergrown Sphalerite crystals, as well. Ex. Charlie Key.
12.2 x 10.1 x 3.7 cm. Old material, classic for the locality but seldom seen today - this specimen is composed of large crystals of tetrahedrite to 3 inches, in a sharp cluster. This locale has produced, I believe, the largest fine crystals of the species with any quality of lustre and sharpness to them. This piece has particularly good stepped growth which gives its face a more 3-dimensional character. It is from the sulfide collection of Dr. Gene Meieran, sold off about 2001 or 2002. Weighs 617 grams.
A highly lustrous and pristine thumbnail cluster of intergrown tetragonal tetrahedrite crsytals from the famous Sweet Home Mine. SUPERB TN! 1.8 x 1.5 x 1.5 cm
