5.7 x 3.5 x1.2 cm. Copper specimens such as this are extremely rare from the historic Carn Brea Mine of Cornwall. This aesthetic, dentritic, floater specimen consists of very sharp spinel-twins, tetrahexahedral and even a few rare cubic crystals. The patina is rich and variable and includes some iridescent crystals. The striking, long spinel-twin with the two, 1 mm flattened cubes at the tip is 3.0 cm. Ex. Charles Pennypacker Collection (1845-1911) - with his handwritten label. He was a well-known contemporary of Bement, Roebling, Jefferis, Vaux and Canfield. Also ex. Dearborn, Scalisi and Borden Collections.
