Peru, Various Minerals and Localities

Peru is a mining country with a great legacy of producing beautiful, rare and interesting mineral specimens.
Here are some interesting proustite, pearceite and acanthite ps argentite specimens from the famous Uchucchacua Mine. Proustite is one of the famous "Ruby Silver" minerals due to its deep red colour. Pearcite is a rare silver sulphosalt, the arsenic-rich end member polymorph of Polybasite.
I picked up the tetrahedrite specimens in Peru a few years ago when I visited that beautiful country.

Item #19171 Bournonite, Quartz, Pyrite 9.0x6.3x4.3 cm Largest Crystal Size: b-8mm $65.00 Huaron Peru Lots of cyclic-twinned, steely-metallic bournonite crystals on the front of this piece associated with clusters of small white quartz crystals and similarly sized golden pyrite crystals.	Item #11659 Quartz, Tetrahedrite 10.8x7.6x8.8 cm Largest Crystal Size: q-50mm, t-16mm $85.00 Mundo Nuevo Mine Mundo Nuevo, Huamachuco Peru A lovely cluster of quartz crystals with a lone tetrahedrite crystal on one side. A couple of the quartx crystals are dinged but most are just fine. Displays extremely well!	Item #19175 Tetrahedrite, Quartz 15.5x10.0x5.2 cm Largest Crystal Size: 4mm $65.00 Julcani Peru The top of this thick plate is covered with hundreds of sharp, tetrahedrite crystals that have crystallized on drusy quartz. Nice crystallized specimen of this ore mineral!	Item #17550 Hubnerite, Quartz 10.1x5.3x3.9 cm Largest Crystal Size: as above $275.00 Mundo Nuevo Mine Huanachuco, La Libertad Peru A superb hubnerite crystal associated with sharp quartz crystals. The hubnerite crystal is doubly terminated and jet-black which make a nice contrast with the white quartz crystals. The hubnetite crystal is a little composite, formed of three main members. Exceptional!
Item #20024 Hubnerite, Quartz 9.6x6.0x5.2 cm Largest Crystal Size: 97mm $175.00 Concuzo Pasto Bueno, Ancash Peru A really nice, elongated, lustrous hubnerite crystal nicely encrusted with white quartz crystals. The hubnerite crystal is dark brown but with deep red internal reflections sparking here and there. The hubnerite crystal is singly terminated and divergent so it has three separate terminations at the terminated end. A little damage to the terminations but sides of the crystal are pristeen. The hubnerite crystal is propped up by quartz crystals and in fact, the hubnerite crystal makes a great matrix for a wonderful quartz cluster! t	Item #26543 Hubnerite, Quartz 5.2x5.6x3.5 cm Largest Crystal Size: h-15mm, qu-21mm $75.00 Mundo Nuevo Mine La Libertad Peru Several sharp, brismatic, black hubnerite crystals are interspersed between clear, well terminated quartz crystals on this attractive specimen. Mundo Nuevo produced some nice specimens before closing!	Item #21257 Pyrite, Calcopyrite, Sphalerite, Quartz 10.9x7.1x5.1 cm Largest Crystal Size: Py -16mm, Ch -27mm, Sp -24mm, Qu -30mm $75.00 Cerro de Pasco Pasco Peru A handsome specimen of large chunky, coated crystals of chalcopyrite associated with some similarly sized sphalerite crystals, long-prismatic, frosted quartz crystals and a few small pyrite cubes here and there. Some of the quartz crystals are broken off towards the back but it displays very well from the front! Good-looking piece! R	Item #22289 Sphalerite, Quartz 16.6x9.5x5.1 cm Largest Crystal Size: 25mm $95.00 Huaron Mine Pasco Peru A large, showy specimen of sphalerite and quartz crystals from this famous mine. Rich! r

Also some chalcopyrite and galena present. Big, showy specimen! R	Item #22799 Tennantite ps Enargite, Pyrite 13.8x11.1x4.0 cm Largest Crystal Size: 16mm $140.00 Julcani Mine Angarres, Huancavelica Peru A large plate of 4mm or so pyrite crystals with a central area of sharp pseudos of tennantite pseudomorphs after enargite. Some small tennatite crystals are on the pseudos. Very nice piece that displays well. R	Item #8829 Enargite, Quartz 8.0x6.4x5.9 cm Largest Crystal Size: 8mm $85.00 Julcani Mine Huancavelica Peru The top of this enargite, quartz and pyrite matrix is covered with sharp enargite crystals and clusters of smaller pyrite crystals. There is another grey sulphide-type mineral, possibly bornite of tetrahedrite present in rounded crystals but I do not know what it is. Nice specimen of this unusual copper mineral!	Item #24351 Hubnerite, Quartz 4.7x3.3x2.6 cm Largest Crystal Size: h-7mm, qu-17mm $35.00 Mundo Nuevo Mine La Libertad Peru A cluster of elongated, tapered quartz crystals studded with smaller, dark brown/black crystals of hubnerite.
