Detailed information
A textural masterpiece, this exquisite specimen is not only beautiful, but is historically significant too. Hollow, rounded, layered aggregates with botryoidal outer surfaces appear to show the classic 'onion skin' form of Native Arsenic, but are replaced by a pale brassy fine-grained Pyrite Group mineral - possibly Marcasite or Lollingite. Then, sat within the open spaces but also on the outer surfaces too, are perfect, small (to 3 mm in length), undamaged prismatic Pyrargyrite crystals of a very dark purple, glossy appearance. Small cabinet in size this is aesthetically stunning and it comes with a very fragile old handwritten label with the number 1833 recorded and I would certainly not be surprised if that was its year of discovery. Clearly a classic from the St. Andreasberg mines, the old label appears to state "Annaberg, Sachsen" which is unlikely. The condition of this piece should not be understated as it is truly remarkable for an old-time classic. There are three old collection numbers attached to the rear of the specimen.
