Brochantite - exceptional large crystals
Chuquicamata Mine, Calama, El Loa Province
Antofagasta Region, Chile
5.6 x 2.5 x 1.6 CM (cabinet)
price: $4500
new year 2021
An extraordinary and important old specimen of Brochantite from Chuquicamata, Ex Schortmann's and Immer Cook collection. The original label dates this to 1948-52, and by far it the best specimen I know of from this famed mine. This is certainly a serious contender for the best of specie outside of the 2016 Milpillas find. Even compared to the Mexican specimens this is a very significant stout cluster. The largest crystal is huge, 4.6 CM tall and quite thick. Close exam of the specimen finds a few slender needle crystals which are more typical of the specie. Under good magnification (40x) a few specks of blue that can be Krohnkite, Bellingerite or Aubertite etc are visible. There are areas of contacting making some rough edges but very little damage. A world class Copper secondary specimen.
