    Description

    MARCASITE
    Northwest Illinois, near Galena
    Marcasite is sometimes known as white iron pyrite because of the close similarity in appearance of the two minerals. In fact, it is a polymorph of pyrite, having the same chemistry but a different structure. This specimen perfectly displays the twinned "cock's comb" orthorhombic crystal structure in the numerous fan-like protuberances that cover its surface, and shines with the characteristic pale brassy metallic luster. The name of marcasite was coined in 1845 after the Arabic word for pyrite, and it was a popular material in Victorian jewelry. In metaphysical crystallography, marcasite is supposed to provide protection to those performing dangerous jobs. This good-sized specimen is quite stable and measures 4¾ x 4½ x 3½ inches.


    Estimate: $1,800 - $2,500.
