Theodor Fahrner - An Art Deco silver, onyx, marcasite and
turquoise cross pendant, Germany circa 1930.
This stunning (and large) cross is in fantastic condition never
having been worn and I have not seen any other examples.
Literature: Theodor Fahrner...between Avantgard and Tradition
and Fahrner-Schmuck 1900 bis 1975.
