7.2 x 5.4 x 3.7 cm. A most unusual specimen with sharp jamesonite crystals, elongated lustrous pyrargyrite, all on a matrix of weirdly crystallized tetrahedrite.
6.5 x 5.3 x 3.5 cm. Yellow tsumcorite druse covers the rich field of sharp tennantite crystals that reach 1.7 cm. The specimen is nicely accented with lustrous dolomite rhombs and a few glassy, amber wulfenite crystals to 4 mm. The backside of the specimen is further complimented with a rich druse of blue-green rosasite. Ex. Willy Israel Collection.
Sharp, intergrown crystals to 1.4 cm with gunmetal luster and accenting quartz. 7 x 6.8 x 6 cm
10.3 x 9.8 x 7.7 cm. An exceptional specimen from old finds here, probably in the 1980s, which features huge tetrahedrite crystals to several inches on size in combination with aesthetic quartz crystals. The specimen is in very good shape, nearly pristine and complete most of the way around the back even. Ex. Francis Allegra collection.
5.3 x 4.0 x 3.7 cm. A rare, for the locality, pyrite with tetrahedrite crystal from the Climax Molybdenum Mine of Colorado. Climax was a bulk, low-grade molybdenum mine and mineral collecting by mine personnel was prohibited. This is a large, sharp, mirror-bright, rich brass-yellow cube nicely accented by a scattering of tetrahedrite crsystals. Ex. Dave Stoudt Collection.
5.2 x 4.6 x 1.6 cm. A fine Peruvian specimen of an elongated 3 cm Tetrahedrite crystal completely covered by lustrous Pyrite crystals, all on a plate of Quartz. Ex. Charlie Key.
4.5 x 3.5 x 3.1 cm. A rare tetrahedrite from this locality. Sharp crystals to 6mm in massive, hefty cluster upon quartz. Ex. Academy of Natural Sciences Philadelphia Collection.
9.9 x 5.2 x 3.1 cm. Chalcostibite on tetrahedite, quartz and sharp disc-shaped calcite, possibly associated with (?) zinkenite. Featuring beautifully lustrous crystals of crystals of Chalcostibite up to 5 mm; arranged in clusters on tetrahedite. Ex. Dr. Werner Paar Collection.
13.0 x 7.5 x 3.0 cm. Spectacular aggregates of platy Chalcostibite crystals arranged in clusters with minor tetrahedite, on a grayish-white matrix of quartz. Ex. Dr. Werner Paar Collection.
5.5 x 3.4 x 1.7 cm. Richard Kosnar mined the Sweet Home for a few years during the late 1970’s and managed to collect some excellent 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 good red color with excellent gemminess. They are sitting atop Tetrahedrite and Pyrite matrix with minor Quartz crystals. Ex. Richard Kosnar Collection.
4.4 x 4.2 x 2.3 cm. Chalcostibite is a rare copper, antimony sulfosalt. This fine combination piece from the Boldut Mine of Romania features shiny, gray metallic blades and needles of chalcostibite clusters scattered on lustrous tetrahedrite crystals and associated with zinkenite, quartz and calcite. Chalcostibite was never common at Cavnic and this major discovery was made in 1990.
5.5 x 2.5 x 1.7 cm. Even though the Sweet Home mine is most famous for its Rhodochrosite specimens, the most significant sulfide in the mine is Tetrahedrite. This specimen hosts several nice Tetrahedrite crystals measuring up to 1.0 cm with good luster, sharpness and a slight amount of iridescent greenish-blue Bornite coating a few of the Tetrahedrite faces. The piece looks like an older specimen (prior to Collector's Edge mining operations), and could have been collected by Richard Kosnar in the late 1970s. Ex. Jaime Bird Collection.

6.5 x 3.8 x 2.2 cm. Richard Kosnar mined the Sweet Home for a few years during the late 1970's and collectwd some excellent Rhodochrosite specimens. This piece features translucent, pink crystals of rhombic Rhodochrosite up to 4 mm which are associated with Tetrahedrite, Quartz, Pyrite and Galena. Ex. Richard Kosnar Collection.
4.2 x 3.3 x 3.0 cm. A brilliantly sharp tetrahedrite just under 1 cm perched on brilliantly sparkling and sharp pyrite cubes. Classic locality combo from this old-time, defunct locality. Ex. Harold Urish Collection.
3.2 x 3.1 x 2.3 cm. Sharp tetrahedrite crystals exceeding 1 cm, on classic sparkling pyrite matrix, from this defunct locale. Ex. Harold Urish Collection.
