Nice example!	Item #27142 Leucophanite, Serandite 2.6x0.9x0.7 cm Largest Crystal Size: L-0.65mm $65.00 Mont Saint-Hilaire Quebec, Canada Here is a small but potent specimen! :) It is a part of a pink, serandite crystal with a light green leucophanite crystal attached. The leucophanite crystal is fluorescent! Rare and unusual specimen.	Item #27141 Pyrite 9.2x8.6 cm Largest Crystal Size: n/a $55.00 Tea Cove Port au Port Peninsula Newfoundland, Canada A more typical sedimentary, shale-formed spheroidal concretion showing the bands of shale imprinted on the outside of the form. A cluster of pyrite crystals clustered on top. You can't tell from the photos but it actually flying saucer shaped! Nice looking piece!	Item #27140 Pyrite 9.7x8.0x4.5 cm Largest Crystal Size: 18mm $65.00 Tea Cove Port au Port Peninsula Newfoundland, Canada This is another interesting piece! It appears to have been part of a larger sheet of pyrite but a part of it that swelled out into a spheroidal concretion with large, sharp cubed of pyrite congregated at one end. Interestingly, the pyrite crystals have amounts of the shale adhering to the middle portion of each cube face sort of resembling inverted hoppers. Very interesting piece!
Item #27139 Pyrite 16.6x14.2x5.3 cm Largest Crystal Size: n/a $85.00 Tea Cove Port au Port Peninsula Newfoundland, Canada A large, flattened, golden potato! Dense! This large concretion has been released from the shale and rumbled around the bottom of the cove for a hundred years or so. Super example! Needs the right amount of postage!	Item #27135 Pyrite 4.7x4.4x3.2 cm Largest Crystal Size: n/a $65.00 Tea Cove Port au Port Peninsula Newfoundland, Canada Here is a flying-saucer/alien vehicle shaped concretion from the Tea Cove locality. Not your normal shape! One side is a smooth disc composed of a mosaic of small crystals while the other side is a kind of oddly shaped mass of tiny crystals with some pyritohedra to 5mm scattered about. Very cool specimen!	Item #27132 Sphalerite 4.3x3.6x2.4 cm Largest Crystal Size: 31mm $40.00 OH Vein, Batchelor Mine Creede Colorado, Canada A cluster of very dark brown, lustrous sphalerite crystals from this famous mining area. Actually, what appears to be two crystals on the right is actually one larger crystal. Complex twinning, as we often see in sphalerite. Nice piece!	Item #27130 Pyrite, Pyrite, ps calcite 4.0x4.5x2.8 cm Largest Crystal Size: 12mm $75.00 Nanisivik Mine Baffin Island Nunavut, Canada This ia highly unusual specimen! The "matrix, is a pyrite cast after, I think, calcite. It shows the form of a calcite crystal inside and under. On the outer side of the cast are complex crystals of pyrite poking out here and there. Interestingly, there is one pyrite on the inside of the cast, which indicates that the coherent pyrite crystals formed after the fine-grained cast. Wonderful!
Item #27128 Galena, Quartz, Sphalerite 7.8x.8.8x8.3 cm Largest Crystal Size: g-27mm, q-18mm $55.00 Madan Bulgaria Here is a verynice cluster of sharp, cool-looking galena crystals on a mound of quartz crystals wit ha couple of black sphalerite crystals. The galena crystals are the feature with sort of tabular and stepped crystals. Looks great!	Item #27127 Millerite 7.5x6.4x4.7 cm Largest Crystal Size: 27mm $75.00 Temagami Mine Temagami Ontario, Canada There are several circular masses(thus really spherical) of millerite embedded in rock matrix. The millerite shows the bright, mirror-like cleavage typical of coarse millerite. There is a seam of chalcopyrite on the bottom of the piece. Unusual specimen from an historic mine!	Item #27123 Arsenic 10.8x10.3x4.0 cm Largest Crystal Size: n/a $140.00 Quiruvilca Mine Santiago de Chuco, La Libertad Peru A huge specimen of mostly native arsenic in botryoidal habit. The arsenic is solid with just a little quartz/pyrite on the back. Amazing arsenic!	Item #27119 Proustite 4.4x2.6x2.3 cm Largest Crystal Size: 2mm $45.00 Imiter Mine Djebel Saghro, Ouarzazate Morocco A larger cluster of ruby-red proustite crystals and a couple of smaller clusters of the sam mineral are in an open space in the top of this corroded, silver-rich galena. There are some platy crystals that I'll assume are polybasite, also in the cavity. "Ruby Silver"!
Item #27116 Silver, Copper 2.3x1.6x0.6 cm Largest Crystal Size: n/a $40.00 Keweenaw Peninsula Michigan, USA The Keweenaw Peninsula s famous for crystallized copper and silver specimens. Another thing it is famous for are these nuggets that are poart silver and part copper. Apparently silver can only "disolve in copper to a certain extent and then afterwards forms a discrete phase as native silver with the copper. Here is an example of that immiscibility!	Item #27115 Tetrahedrite, Quartz 6.0x4.7x3.0 cm Largest Crystal Size: 20mm $85.00 Naica Chihuahua Mexico A couple of sharp, tetrahedral crystals of tetrahedrite, along with some smaller ones are formed amongst sharp, milky quartz crystals. One of the lesser known minerals from this famous locality.	Item #27113 Pyrite 9.4x4.8x2.8 cm Largest Crystal Size: 12mm $40.00 Sherman Mine Temagami Ontario, Canada Here is a good looking specimen from a long-closed iron mine in northern Ontario. The Sherman Mine is normally famous for the jasper-magnetite-hematite banded ore that they mined there. Here is something a little different, pyrite crystals in and on a shale-like rock matrix. The specimen is repaired but, done well and looks great!	Item #27109 Galkhaite 4.8x2.7x2.6 cm Largest Crystal Size: 0.5mm $65.00 Getchell Mine Humboldt County Nevada, USA This specimen has a number of sharp, cubic crystals of galkhaite on it. Little red arrows have conveniently been placed on the piece to better enable you to find and see them with your loupe or 'scope. Nice specimen of a rare mineral1
Item #27104 Arsenic 5.0x4.2x2.8 cm Largest Crystal Size: n/a $65.00 Edward Island Lake Superior Ontario, Canada A solid piece of native arsenic in botryoidal form from a little known locality near the north shore of lake Superior. The locality was a prospect over a hundred years ago!!	Item #27102 Pentlandite, Chalcopyrite, pyrrhotite 7.7x7.0x3.3 cm Largest Crystal Size: 7mm cleavages $75.00 Levack Mine Levack Township Ontario, Canada This is a rich specimen of nickel-copper ore from sudbury. It is well above average grade and you can actually see the cleavages of pentlandite embedded in the other sulphides. Pentlandite is a relatively rare mineral that never occurs in free-standing crystals. Here is an excellent example!	Item #27101 Dolomite, Marcasite, Pyrite, ps marcasite 6.4X4.2X4.2 cm Largest Crystal Size: 31mm $40.00 Nanisivik Mine Baffin Island Nunavut, Canada Dolomite often occurs in, curved "saddle shaped" crystals. Here is an exemplary example of that form. This highly curved crystal shows a very exaggerated curved rhombohedral form and is nicely perched on bladed, pyrite pseudomorphs after marcasite. As well, the dolomite crystal is speckled with small marcasite crystals. Very interesting piece from the long-closed Nanisivik Mine!	Item #27100 Quartz, Pyrite 5.1x3.7x2.0 cm Largest Crystal Size: q24mm $40.00 Nanisivik Mine Baffin Island Nunavut, Canada A cluster of doubly-terminated, colourless, sharp quartz crystals associated with a couple of bladed pyrite pseudos after marcasite. Quartz is one of the lesser seen minerals at the Nanisivik Mine!
