This is a beautiful and sculptural, large cabinet specimen. The surreal sea-green color of the lustrous aragonite is due to copper inclusions. Note the obvious presence of a rare green mineral in small, sharp crystals: probably libethenite or brochantite. Both are found at the mine, and I have a sample sent out for analysis. Ex. Academy of Natural Sciences Philadelphia Collection and obtained by Sam Gordon on one of his several trips to South America in the 1920s and 1930s for the Academy. Very rare, unusually beautiful, old-time material.
