Mined, in the 1830's, this old-timer has quite a pedigree. The specimen consists of a pair of translucent 1.3 cm half-cyclic twins with excellent luster and good honey-brown color sitting on partially crystallized Galena. Both minerals are contacted or broken along the back, but that is not visible at all from the presentation side. It is a lucky miracle that this fine old classic has survived even this long. This is an excellent specimen. (ex. Archduke Stefan of Saxony Collection, via Martin Ehrmann from the Musuem of Bern to Richard Kosnar in the 1960s) More information about the Archduke is available at http://minrec.org/labels.asp?colid=596
