Outstanding pseudo-hexagonal compound twins of Aragonite, with the largest crystal being an amazing 7.7 cm in length. These translucent to gemmy, white to clear crystals form sharp prisms with incredibly bright luster. They are generally sharp, with an occasionally stepped face. Remarkably clean from damage - these are exceptional crystals of Aragonite from one of the most classic old locales in Europe. Herb Obodda had a special suite of Herrengrund minerals assembled over decades of collecting, of which this was a part. Much better in person, as shooting monochromatic lustrous crystals is difficult! It was once owned by the great collector Clarence Bement, (1843-1923) (http://www.minrec.org/labels.asp?colid=139), who paid $14 for this in the late 1800s, according to accession records (provided) from the American Museum of Natural History. This piece would have been in his collection when it was purchased by financier JP Morgan in 1910 and donated to the museum. Ex. Bement, AMNH. Great history, and a great piece.
