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 #19176 Tetrahedrite, Calcite 10.0x8.2x3.5 cm Largest Crystal Size: 15mm $160.00 Huaron Peru A superb plate of sharp tetrahedrite crystals that totally cover a matrix of sphalerite and pyrite. The tetrahedrite crystals have a coating of preferentially deposited, tiny, white calcite crystals that have formed on just one side of the crystals. Sort of like snow on tree branches. Nice!	Item #11659 Quartz, Tetrahedrite 10.8x7.6x8.8 cm Largest Crystal Size: q-50mm, t-16mm $125.00 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 #15395 Augelite, Quartz 3.3x2.1x2.0 cm Largest Crystal Size: 11mm $45.00 Mundo Nuevo Mine Huamachuco, La Libertad Peru A small plate of quartz crystals sporting two very nice augelite crystals. The larger of the crystals is a pleasant green colour and is very well formed. Very good example.
Item #19175 Tetrahedrite, Quartz 15.5x10.0x5.2 cm Largest Crystal Size: 4mm $75.00 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 $275.00 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 #20683 Bournonite, Sphalerite 7.5x6.1x2.6 cm Largest Crystal Size: 8mm $75.00 Pachapaqui Bolognesi Ancash, Peru This specimen has a number of well-formed bournonite crystals on a matrix of dark brown sphalerite crystals. Handsome specimen that displays well.

Some of the quartz crystals are broken off towards the back but it displays very well from the front! Good-looking piece! R	Item #22089 Quartz, Sphalerite 10.2x7.3x4.2 cm Largest Crystal Size: qu 2mm, sp 25mm $65.00 Huaron Mine Huayllay Pasco, Peru Sweet-looking, very lustrous dark-brown sphalerite crystals partially covered by sparkling crystals of white-colourless quartz crystals.

The enargite crystals have an oriented overgrowth of chalcopyrite on the prism faces. One of the great localities! Looks great. r
