ACR-UJTTennantite Subgroup Cu6(Cu4C2+2)As4S12S , Pyrite FeS2
Dimensions: 60 mm x 35 mm x 20 mm
Weight: 43.3 g
An intergrown cluster of sharp black tetrahedral tennantite crystals up to about 2 cm dusted for the most part with tiny pyrite crystals. Well at least I think they are tennantite. Bought the specimen at the mine. The scale under the specimen is an inch with a rule at one cm.
L0Q-68KSphalerite ZnS , Pyrite FeS2
Dimensions: 50 mm x 35 mm x 30 mm
Weight: 98.6 g
Black somewhat iridescent intergrown sphalerite crystals to about 2.5 cm with a dab of small pyrite crystals at their base with a few DGNs (damn grey needles.) Bought the specimen at the mine. The scale under the specimen is an inch with a rule at one cm.
VMN-HYCAugelite Al2(PO4)(OH)3
Dimensions: 40 mm x 30 mm x 30 mm
Weight: 31 g
A cream colored doubly terminated prismatic augelite crystal of about 2 cm on a limonite matrix with a few other smaller augelites. Selected from a lot of about 500 other specimens of Augelite. Machacamarca is one of the earliest silver mining districts in Bolivia. It is credited with having the first bank in all of Bolivia, even before Potosi. It is built up and down a little tight canyon with mine dumps spilling into the canyon from both sides. The scale under the specimen is an inch with a rule at one cm.
59L-VNPHematite Fe2O3 , Quartz SiO2
Dimensions: 60 mm x 40 mm x 40 mm
Weight: 106.3 g
A high domed cabochon of transparent light colored smoky quartz with a flat window cut on one side showing a thin hexagonal black crystal of hematite about a cm in diameter growing up into the quartz. Selected from a ~50 kg lot of polished quartz with inclusions in Curvelo, Brazil. One would think that the specimen is from the sand stone area in Minas Gerais rather than the pegmatite area. The scale under the specimen is an inch with a rule at one cm.
EXK-7DGCopper Cu
Dimensions: 40 mm x 30 mm x 30 mm
Weight: 72 g
A mass of small copper crystals growing on some dark, perhaps a little charred, wood. X Cureton Mineral Co. The scale under the specimen is an inch with a rule at one cm.
PKH-K38Chrysocolla Cu2-xAlx(H2-xSi2O5)(OH)4·nH2O, x < 1 , Malachite Cu2(CO3)(OH)2
Dimensions: 60 mm x 45 mm x 20 mm
Weight: 95.6 g
A hand sized polished nugget of chrysocolla, malachite and other minerals. This massive material has been mined in Ica since the 1970s, A lot of it was sold to customers in Israel to be cut up and sold to tourists as Elat stone which was a similar material that in ancient times was found in the region. It is still being dug and cut and polished into balls, eggs and other lapidary items by lapidaries in Lima. The quality is highly variable. The scale under the specimen is an inch with a rule at one cm.
07F-WTLAzurite Cu3(CO3)2(OH)2
Dimensions: 40 mm x 40 mm x 30 mm
Weight: 57.5 g
A floater nodule of small shiny blue crystals. Specimen selected from a 1000 kg lot of similar specimens. There were few good specimens in shipment. The scale under the specimen is an inch with a rule at one cm.

Dimensions: 55 mm x 30 mm x 20 mm
Weight: 7065 g
An over polished quartz crystal with thick golden rutile crystal sprays included. Taken from a large shipment of included crystals. The scale under the specimen is an inch with a rule at one cm.
