A branching group of copper crystals, freed from the enclosing analcime, on basalt. The copper crystals include a nice red cuprite patina in places, contrasting with the green basalt. Collected in October 2021.
About These Copper Specimens
Copper has been known at Cap D’Or for at least two thousand years. Collection-quality specimens have been recovered sporadically from the shoreline basalt cliffs and outcrops, usually in isolated finds of single or small numbers of pieces. The period 2011-2013 was more productive, and since then finds have been few and far between.
