A HIGHLY UNCOMMON and STRIKING combination piece from the famous Sweet Home Mine. Bright green malachite coats well-crystallized, lustrous tetrahedrite crystals to 8 mm. 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 and quartz needles. There were only about 2 DOZEN pieces from this pocket and I managed to get almost all of the very best ones. Malachite had never been found from the mine before this, and it had to be analysed to prove its reality. My last piece (i think), found surfing the drawers recently. These were found around 3 years ago. 5.9 x 4.8 x 3.0 cm
A BEAUTIFUL, perfect, brilliant-metallic, 1.9 cm, tetragonal tetrahedrite crystal nested on very light, pastel-pink manganoan calcite on sulfide matrix. This is old-time Peruvian material from the 1970s or early 80s from the stock of dealer Dr. Gary Hansen. The label says Huanuco Dept., but review of the Mineralogical Record Peru Special Issue, indicates that the piece is most likely from the Pachapaqui District in Ancash Dept. 6.9 x 4.5 x 2.7 cm
Gemmy pink rhodo crystals, with a single 1.5-cm tetrahedrite and gemmy little quartz needles. There is some minimal but visual damage to the rhodo crystals, so this piece is more about the nice combo. 4.2 x 2.7 x 2.2cm
This specimen was probably donated to Lafayette College in Pennsylvania by professor Art Montgomery, one of the top field collectors/ mineral dealers the U.S.A. has ever produced. The specimen features lustrous, mirror bright, equant, black crystals, to 1.5 cm across, along with colorless, lustrous quartz crystals, to .5 cm across. 6.9 x 5.0 x 4.6 cm
The defunct Bingham open pit, a huge disseminated deposit, was never known for crystallized specimens. Therefore, this specimen of bright, dark gray, tetrahedrite crystals, to .3 cm across, nestled among colorless, lustrous, translucent quartz crystals, to .7 cm in length, is a rare specimen! 4.0 x 2.8 x 2.2 cm
Large, pyramidal, slate-gray crystals of tetrahedrite, to 3.5 cm in length, have grown in and around translucent, pastel gray, crystals of quartz which reach the same length. There does not appear to be any damage or contact except at the extreme periphery of this matrix specimen. The tetra cluster just floats up there, perfect as can be! Very rare in such aesthetic form! 9 x 7.8 x 5.5 cm
A large, chunky, finely-formed compound crystal of tetrahedrite, with sharp faces all over it. This specimen came out of the collection of noted California collector Gene Meieran. 6.9 x 5.4 x 2.5 cm
I know Mark...he collects bornite and bought this for the superb BORNITE crystallization evident throughout the lower part of the specimen! For the rest of us, though, that beautiful and sharp purple fluorite is the focal point, and for this it has a real value as an aesthetic fluorite from this mine. 5.6 x 4.6 x 3.3 cm
Sharp crystals to 1 cm of this rare mercurian-rich varietal of tetrahedrite, from the classic locality for this species in Europe. Once, this was a valid species in its own right, actually. A rich specimen, overall, that frankly displays better vertically compared to how it is shown
Sharp crystals to 1.3 cm of this rare mercurian-rich varietal of tetrahedrite, from the classic locality for this species in Europe. Once, this was a valid species in its own right, actually. A rich specimen, this is actually fairly aesthetic because of the nice contrast to the talc matrix!
A most unusual specimen with sharp jamesonite crystals, elongated lustrous pyrargyrite, all on a matrix of weirdly crystallized tetrahedrite. This has a label handwritten by Federico Ahlfeld, a very famous mineralogist and

A rare tetrahedrite from this locality. Sharp crystals to 6mm in massive, hefty cluster upon quartz

Large, pyramidal, slate-gray crystals of Chalcopyrite coated with Tetrahedrite , to 3.5 cm in length, have grown in and around translucent, pastel gray, crystals of quartz which reach the same length. There does not appear to be any damage or contact except at the extreme periphery of this matrix specimen. The cluster just floats up there, perfect as can be! Very rare in such aesthetic form!
