Cluster of black tabular Enargite crystals to 7mm on a bit of Baryte matrix.
This specimen comes with a label from the Abe Rosenzweig Collection, a well known collector, dealer, and teacher and the Oberlin, Ohio address dates it between 1970 and 1977, so it's more vintage than antique. Additionally, he was the author of the paper titled 'Zonal Composition of Luzonite-Famatinite and Enargite from the Chinkuashih Mine, Taiwan' published by the Geological Society of China in 1975.

It was tough to get good photos of the Enargite. They are highly reflective with their mirror-like reflectivity. The crystals reach 6mm and there are several of them in a pocket 3.5cm wide. Very nice specimen. Collected by Arnold in 1959.
