6.8 x 6.1 x 2.3 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 great red color with excellent sharpness and gemminess. They are associated with minor reddish hübnerite and black tetrahedrite on thin "needle" quartz crystal matrix. The largest rhodochrosite crystal measures 2.3 cm across, and despite a contact, has superb color and internal gemminess. This mine is now completely defunct, and will never produce these world class quality rhodochrosite specimens again. This is a good miniature with fine color and an attractive color contrast between the red rhodochrosite and black tetrahedrite. Ex. Richard Kosnar Collection.
6.7 x 5.2 x 5.1 cm. These are some of the most recognizable Manganoan Calcite specimens in the world. This particular piece features several aesthetic, "feathery" pink scalenohedral crystals of Manganoan Calcite associated with minor black Tetrahedrite and Quartz. These Calcites have a truly unique look to them. These pieces are no longer being mined, and are now some of the great "classics" from Peru.
Big (over 2 cm), super-shiny metallic (it is hard to capture this flashy luster in the pics) crystals of tetrahedrite, intergrown with gemmy quartz crystals. The tetrahedrites have razor-sharp faces and fine terminations. 6.7 x 6.4 x 3.2 cm
I bought most of the top specimens from this small 1-time, unprecedented pocket. This specimen features lustrous, black 1-cm size tedrahedrite crystals associated with tufted ,bright green malachite,an occasional frosted lilac fluorite crystal and a few mm size light pink rhodo rhombs. This colorful combination sits on white quartz vein matrix. For the pocket, it is quite rich in good isolated malachite balls. 5.8 x 3.2 x 2.8 cm
10 x 8.4 x 4.8 cm. This is a very appealing rhodochrosite, unusual in its combination with both fluorite and tetrahedrite. The tetrahedrite occurs as sharp, metallic crystals and may actually be overtopping large bornite crystals, it seems. The piece is very nearly pristine, and no restoration or repairs whatsoever. The large central crystal is 5 cm across, and it is draped with fluorite and smaller rhodochrosite crystals. The lustre is high, and the color saturation is uniform. This is an excellent piece overall, and has a huge amount of color, considering what else I have seen on the market these days. The fluorites are sparkling and a nice lavender hue, in person. I acquired this piece for my private collection, of fine large Sweet Home rhodochrosite specimens, in 2006 at the Munich show. Ex. Rob Lavinsky Collection.
This piece is extremely sculptural with 2cm lustrous,black tetrahedrites jutting out of a valley of quartz crystals and green malachite along with minor lilac fluorite and rhodochrosite. From the single pocket of malachite found at this mine and considered quite a rarity! i bought the best of them, about 6 months ago, and this is one from that lot. VERY IMPORTANT locality specimen! 7.5 x 3.3 x 3 cm
8.2 x 5.0 x 3.8 cm. There was a small pocket that produced these Tetrahedrite specimens about 7 years ago (~2002), and they are some of the finest quality Tetrahedrite specimens that I have seen from Bolivia. This specimen features dozens of tetrahedrons with very sharp faces and extremely highly luster on matrix. The crystals (the largest measuring 1.2 cm across) have many small tetrahedral "hillocks" covering the faces which make for a very unique "ripple" effect on all sides.
9.2 x 7.2 x 4.5 cm. Classic, old-time material from the famous mines at Cavnic, Romania. Lustrous, sharp, steel-gray tetrahedrite tetrahedrons to 2.2 cm cover the matrix of quartz and minor sphalerite. Ex. Hans Karabacek, Mitch Gunnell and Dr. Bob Byers Collections. Karabacek was a noted Austrian collector who lived from 1878 to 1963 and was known for collecting only the best of specimens. Accompanied by a handwritten Karabacek label. Rich and excellent material with a great provenance. The Karabacek collection mostly ended up in Harvard and pieces today are seldom seen for sale.
A large, beautiful and flashy specimen featuring sharp, bright tetrahedrites combined with equally sharp, bright & brassy chalcopyrites, in a perfect balance! Little clusters of quartz add a pleasing accent. The tetrahedrites measure up to 1.5 cm and the chalcopyrites to 2 cm. BETTER IN PERSON AND BRILIANTLY SHOWY IN A CASE! 14.2 x 12.0 x 3.3 cm
Sometimes it is simply amazing how pretty and aesthetic a "black" mineral can be. The wonderful 3-dimensional crystal habit and excellent metallic luster combine to make this a real killer for the species! It has minor edge wear that, I think, can be excused given the other qualities 3.7 x 3 x 3 cm
Cubes of purple fluorite, intergrown with gemmy quartz needles, on a matrix of tetrahedrite and pyrite. Sparkling and colorful! 5.4 x 4.3 x 2.6 cm
A HIGHLY UNCOMMON and striking combination piece from the famous Sweet Home Mine. Bright green malachite coats well-crystallized, lustrous tetrahedrite crystals to 2.0 cm. Beautifully contrasting transparent to frosted purple fluorite cubes to 4 mm add to the panache of this piece. There is also a few tiny rhodochrosite crystals. There were only about 2 DOZEN pieces from this pocket and I managed to get most of the very best ones. Thought all were sold but found 2 left, recently.With the closing of the Sweet Home Mine, your opportunity to obtain one of these is literally gone. Malachite has always been rare from the mine and this combo piece is superb. 5.2 x 4.9 x 3.0 cm
A beautiful and aesthetic plate of gemmy and lustrous, cherry-red rhodochrosite rhombs to 1.3 cm on needle quartz matrix with nicely contrasting tetrahedrite crystals from the famous and now-closed Sweet Home Mine. Prices continue to escalate since the mine closed. Super trivial bruising on one rhomb is barely noticeable. This piece has very rich color and good lustre 5.1 x 4.5 x 2.1 cm
A SUPERB, AESTHETIC and pristine sulfide combination piece from the Hauron District of Peru. A cluster of highly lustrous, black sphalerite crystals sits in a valley surrounded by "mountains" of bright, brass-yellow, twinned chalcopyrite crystals. The twinned chalcopyrite faces have different reflectivity due to the reflection of light off of microscopic tetrahedrite crystals. CHOICE material from the Gene Meieran sulfide collection. 6.2 x 5.7 x 1.8 cm
Beautiful twin with superb habit and very attractive drusy surface. The crystal is so sharp that, if you follow the twinning plane down, there is an extremely attractive little triangular face right at the base of the plane. It is barely visible in the photos because of the lighting angles, but it stands out beautifully in person. Just a contact on the back and one tiny ding, otherwise perfect all over. This is quite the aesthetic thumb and incredible for the species, especially from a US locality. 1.5 x 1.4 x 1.3 cm
