Chalcopyrite on Sphalerite w. Pyrite-
stock #17.1-A19-098
Casapalca Mine, Casapalca, Huarochiri Province
Lima Department, Peru
9.8 x 7.2 x 5.2 CM (cabinet)
price: $480
new june 17

An outstanding cabinet display piece of fine, large (to 4.5 CM) crystals of iridescent Chalcopyrite on contrasting Sphalerite. Although Chalcopyrite is a common mineral, great crystals especially large ones are surprisingly rare. The patina and metallic color play make this especially attractive. An older Casapalca specimen in fine condition overall, with a few small chips mostly on outer edges. As Chalcopyrite is very brittle it is rare to have such large crystals in this fine condition.
Tetrahedrite - Highly lustrous crystals

Casapalca Mine, Casapalca, Huarochiri Province
Lima Department, Peru
6.8 x 6.1 x 2.8 CM (cabinet)

Spring 2017

Metallic and bright lustrous these very sharp crystals are sprinkled with a few small quartz and pyrite crystals. Individual tetrahedrons up to 2.7 CM are jumbled in a complex arrangement on this matrix plate. In fine condition overall for this delicate mineral, only one crystal has an edge bruise, all others are perfect, complete and pristine. Really hard to find this level of quality at any price.
