Item #14045 Stibnite 7.5x7.2x5.3 cm Largest Crystal Size: 35mm $140.00 Baia Sprie Romania This is a very showy specimen of the Romanian stibnite. It is a fine cluster of well formed, elongated, well-terminated stibnite crystals that displays perfectly. Stands just like in the photo for display. Excellent!	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 #20912 Boulangerite, Quartz 12.9x7.0x3.2 cm Largest Crystal Size: Bo 8mm, Qu 20mm $75.00 Zacatecas Mexico Classic Zacatecas! Fine, hairy boulangerite crystals are on and between all of the quartz crystals on this cluster. Very nice!	Item #22354 Sphalerite 4.2x4.0x2.2 cm Largest Crystal Size: 30mm cluster $55.00 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!

THE classic association that we often see from the Eagle Mine, now long closed. Shows well!	Item #22540 Tennantite 8.0x6.5x3.9 cm Largest Crystal Size: 9mm $85.00 Butte Montana, USA A very nice specimen showing a plate of lead-grey-metallic tennantite crystals nestled amongst small, colourless quartz 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 #26710 Enargite, Quartz 9.3x5.4x2.4 cm Largest Crystal Size: 13mm $150.00 Leonard Mine Butte, Silver Bow Co. Montana, USA Here is a hard to come by, good-looking plate of enargite crystals from the famous Butte Locality. There is bruising on a number of the crystals but there are many unbruised enargite crystals, as well. Half of the specimen has many of the enargite crystals, draped with little blankets of tiny quartz crystals for a nice accent. Displays very well.	Item #24654 Millerite 4.8x3.8x2.2 cm Largest Crystal Size: 6mm $35.00 Halls Gap Lincoln County Kentucky, USA This silica geode has many fine, hairlike millerite crystals in it. The crystals are very fine, golden hairs that criss-cross across the open space. Nice! s	Item #24655 Millerite 3.6x2.6x3.5 cm Largest Crystal Size: 5mm $35.00 Halls Gap Lincoln County Kentucky, USA Lots of golden, hairlike, prismatice crystals of this nickel sulphide mineral stick out of the silica lining of this geode from the famous Hall's Gap area of Kentucky. Classic! s	Item #24656 Millerite 4.9x4.0x3.0 cm Largest Crystal Size: 8mm $45.00 Halls Gap Lincoln County Kentucky, USA Nests of golden millerite needles are present on the chalcedony lining of this geode from the Famous Hall's Gap area. There are also some spiky crystals that may be millerite but I'm not sure. Interesting piece! s
Item #25066 Bournonite 3.9x2.4x3.0 cm Largest Crystal Size: 15mm $65.00 Les Malignes Mine France A cluster of characteristically sharp, yet rounded bournonite crystals from this locality that is famous for this mineral. The apparently, rounded crystals are actually composed of very small stepped faces in this specimen. French classic!	Item #25950 Arsenopyrite 3.3x2.0x1.7 cm Largest Crystal Size: as above $45.00 Jardine Montana, USA A twinned, crystal of arsenopyrite that is oxidized on the outer surface. The crystal is not complete and is missing part of the crystal on the backside. Still, an interesting crystal from an interesting locality.	Item #26446 Millerite, Quartz 2.8x3.1x1.2 cm Largest Crystal Size: 10mm $40.00 Hall's Gap Kentucky, USA A wonderful quartz-lined geode that contains a wonderful swirling, curling array of acicular millerite crystals.

Item #27232 Nickeline 3.9x1.5x1.6 cm Largest Crystal Size: 1mm $45.00 Helba Eisleben Germany There are a number of small but very sharp nickeline crystals exposed against country rock in a small calcite vein running through this piece. I think some of the calcite could be removed to expose some additional excellent nickeline crystals.
