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 #29322 Seligmannite, Galena 5.8x4.1x2.3 cm Largest Crystal Size: 0.5mm, 7mm $40.00 La Palomo Mine Castrovirreyna, Huancavelica Peru Loads of small, sharp, lustrous, prismatic crystals of this rare mineral on this matrix of corroded galena and sphalerite. Nice seligmannite crystals!	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.

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

Item #29324 Seligmannite, Galena 5.3x4.1x3.9 cm Largest Crystal Size: 1mm, 15mm $45.00 La Palomo Mine Castrovirreyna, Huancavelica Peru The galena crystals are actually fairly sharp, spinel-twinned crystals that hare speckled with tiny, sharp, prismatic seligmannite crystals, mostly under 0.5mm.
