A group of excellent copper crystals on basalt – these are sharp crystals! Nice lustre, with some red patina due to cuprite/oxidation. 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.
