Nagyagite specimens from the famous Type Locality of Nagyag (now called Sacarimb), Romania are quite rare. The splendent, laminar crystals in this one are of considerable size and well defined for the species, up to 2.6 cm. This outstanding, two-sided, combination specimen also has long, dendritic, hair-like crystals of sylvanite to 1.9 cm on one side and matte-black sphalerite crystals on both sides. This excellent and classic, old-time piece probably dates to the 1800s, but no proof. Ex. Eric Asselborn Collection.
