Item #13073 Galena, Quartz 6.0x4.0x2.1 cm Largest Crystal Size: 23mm $40.00 Nikolaevskiy Mine Dal'negorsk, Primorskiy Kray Russia A very nice cube-octahedron of galena tucked away between white quartz crystals. Classic Locality! Looks very nice.	Item #10351 Tetrahedrite 6.3x5.4x3.3 cm Largest Crystal Size: 10mm $50.00 Huaron Mine Cerro de Pasco, Pasco Dept. Peru This concave, almost geode-like matrix of silica is lined with sharp, black kind of composite tetrahedra of tetrahedrite along with sharp, smaller galena crystals and a little chalcopyrite. Very interesting and unique! Looks great. ex John Dagenais collection.	Item #12243 Cobaltite 3.1x2.9x2.3 cm Largest Crystal Size: 7mm $45.00 Brazil Lake Espanola Ontario, Canada This specimen features a above average sized cube that has been naturally fractured but held in place by post-drack mineralization. Lots of smaller, sharp crystals on the sides and back of the specimen. Displays very well.	Item #19290 Stibnite 16.5x1.6x2.0 cm Largest Crystal Size: as above $65.00 Xikuang Shan Mine Leng Shui Jiang, Hunan China This specimen is a long, lead-grey lustrous crystal of stibnite, that is terminated at one end. In the typical manner of stibnite, it diverges from itself, splits into two crystals and is heavily striated. There are some small barite crystals attached. Sweet!
Item #20260 Sphalerite, Siderite, Pyrite 6.3x6.7x5.4 cm Largest Crystal Size: Sp-9mm, Si-10mm $85.00 Eagle Mine Gilman, Eagle Co. Colorado, USA An excellent representation of the main mineralization at this long-closed mine. The front of this quartz matrix is covered by sphalerite crystals with a few, disc-like siderites and sprinkles of tiny, sparkling, pyrite crystals.	Item #20659 Galena 9.7x6.4x3.9 cm Largest Crystal Size: 20mm $85.00 Level 450/500, Block 22 Kruchev Dol Mine, Madan Bulgaria A plate of galena crystals from this modern day, classic locality. It is difficult to see but his is, in fact, one big spinel law twin and that is why the crystals appear to be in parallel. On one side, the crystals have that rounded appearance that we sometimes see from Madan. Just partially. The rest of the crystals are exceedingly sharp! Excellent luster. Very nice piece.	Item #21158 Bournonite, Fluorite 1.8x1.7x1.2 cm Largest Crystal Size: as above $95.00 Yaogangxian Mine Chenzhou City, Hunan China This is a classly little specimen! It is a doubly terminated, lustrous, twinned bournonite crystal that has a few fluorite cubes on it. The bournonite is striated with prominent re-entrant angles with very lustrous terminations. The fluorite is in cubes that are a peculiar milky-light-purple colour. Very nice! t	Item #21163 Galena 8.3x6.5x4.5 cm Largest Crystal Size: 19mm $85.00 Neudorf Harz Mountains Germany The top-front of this carbonate matrix is totally covered with gunmetal-blue galena crystals. Some of the crystals have chafed corners but overall, the specimen looks good! Displays well. t
Item #21267 Nickel-Skutterudite 8.0x6.0x2.2 cm Largest Crystal Size: As above $75.00 Schnepfenbusch Mine Baumhaus, Hesse Germany A superb specimen of solid, banded arsenide mineralization from this famous old area. The specimen comes with an old H. Westengerger label that states there is "Cloanthite", Safflorite and Rammelsbergite in the bands. Also accompanied by a Dakota Matrix label that calls it Nickel-Skutterudite or "Cloanthite". Very rich, interesting specimen, saw and polished on one side to best show the mineralogical texture. Rough on the other sides. R	Item #21589 Pyrite, Quartz 6.2x3.8x2.7 cm Largest Crystal Size: 4mm $35.00 Tuscany Italy Just a nice cluster of shiny, sharp, pyritohedral, pyrite crystals, encrusted with small, elongate-prismatic, white quartz crystals. Famous Italian mineral area!	Item #22139 Pyrite 10.0x2.4x1.4 cm Largest Crystal Size: 9mm $35.00 Stanstead Quebec, Canada A sweet, almost perfect pyrite crystal partially embedded (repaired) in dark grey metasediments. The crystal is a slightly elongated cube with just a tiny chip out of one corner, a miracle considering it was totally embedded in the rock, at one time! Nice light matte patina. Easy to look at!	Item #22354 Sphalerite 4.2x4.0x2.2 cm Largest Crystal Size: 30mm cluster $65.00 Elmwood Mine Carthage Tennessee, USA A complex, very dark brown sphalerite crystal is well exposed on this matrix of creamy-white dolomite crystals. Displays very well. One of the nicest sphalerite crystal locations in modern times!
Item #22536 Siderite, Sphalerite 11.9x8.4x2.0 cm Largest Crystal Size: Si 5mm, Sp 8mm $160.00 Eagle Mine Gilman Colorado, USA A large specimen of massive, coarse grained sulphides with the top covered with sharp sphalerite and siderite crystals.

The tennantites are simple tetrahedra with truncated corners. A larger, quartz crystal on top adds a nice accent although has a bruised termination.	Item #22910 Marcasite, Pyrite, Galena, Dolomite 5.2x4.6x4.0 cm Largest Crystal Size: g-16mm $40.00 Bixby Missouri, USA A myriad of tiny pyrite and marcasite crystals largely coat cube-octahedral galena crystals. Nice locality piece from this famous "Tri-State" mining area.
