Chalcopyrite with Galena, Pyrite and Calcite
stock #16.1-684
Rodna, Rodna Mountains
Bistrita-Nasaud County, Romania
8.9 x 6.4 x 4 CM (cabinet)
price: $225
Worldwide mix summer

From an older European collection, these are well formed, fine Chalcopyrites with some complex Galena all dusted with Calcites. The original label lists this as from Rodna, but it is unlike any other example we have seen from the locale, and unlike any of the better known Romanian localities (Cavnic, Turt etc). As often happens with old collections we can not always fully trust the locality information, but if correct this is especially fine for the locality and a significant older Roumanian piece with character. Undamaged. The Chalcopyrites reach 2.6 CM and are textbook sharp.
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.
SOLD Chalcopyrite and Quartz -classic locale
stock #SOLD 16.1-351
Saint Agnes
Cornwall, England
8.6 x 6.8 x 2.4 CM (cabinet)
price: $190
new june 17

A Cornish Chalcopyrite that is well crystallized and with good luster. Sharp trigons to 1.7 CM across are scattered on a thin plate with stained Quartz crystals between each. Ex Huber collection (Austria), in good condition there is some Quartz or Calcite overgrowths on some Chalcopyrites, and Pyrite is present in the matrix.
Chalcopyrite (skeletal Crystals) and Enstatite
stock #9.1-165
French Creek Mines, St Peters, Chester Co.
Pennsylvania, United States
4.5 x 3.2 CM (miniature)
price: $350

A delicate and esthetic classic. The early French Creek Chalcos are distinctive and very much sought after, they are definately the most desired US chalcopyrites. The skeletal growth structures make very intricate geometric forms that are well presented here. The enstatite crystals reach 1.6 CM and are all terminated. These make a fine contrast and the overall presentaion is very fine.
SOLD Chalcopyrite (large elongated crystal)
stock #SOLD 8.1-442
Krushev Dol Mine, Madan, Rhodope Mts.
Madan, Bulgaria
6.2 x 4.4 x 2.7 CM (small cabinet/ large miniature)
price: $0

A single, big, elongated chalcopyrite crystal showing fine striations and luster. Most faces are perfect and shiny, but there is slight chipping on a few edges, not significant given the size of the crystal. Although Chalcopyrite is a common mineral, crystals that are complete of this size are rare. Madan has produced a few superb examples.
