ID: CC32803
Carn Brea mine formerly lay in the district of Illogan at the northern foot of Carn Brea, an elongated hill formed from a satellite granite offshoot of the more southerly Carnmenellis Pluton. This mine produced many fine specimens of several species, yet it is Bornite which first springs to most collector’s minds. This is a first rate, top quality large miniature/small cabinet specimen, composed of intergrown stacks of sharp, finely crystallised Bornite crystals forming individual columns approaching 2 cm long. The intergrown columns form a solid metallic mass, yet with much remaining void space between the stacks, in some instances providing narrow peepholes to look through the entire specimen. One side is fresher that the opposite, the latter appearing more oxidised with an earthy texture and matt, deep damson, dark maroon and bluish patina. The Bornite crystals on the opposite face are a more steely battleship grey with a metallic lustre and speckled, patchy iridescence. A beautiful example of Bornite from Carn Brea mine.
