Art Deco ring with onyx, coral, green tourmalines, and marcasites, in sterling silver, by Theodor Fahrner. Striking and dramatic, this ring shows Art Deco design at its finest. The center faceted onyx is flanked by opposing diagonals of natural coral stone and tourmalines, with complex arrangements of marcasites on all sides.
The ring is a Theodor Fahrner piece without its hallmark and with replaced stones. The face of the ring measures 1-1/4" by 11/16", presenting as a tall and wide ring for its 5-1/2 finger size; it was probably a size 7 originally. Unmarked but tested, the shank was sized smaller, removing the Theodor Fahrner hallmark. If you look closely at the back, you can see where the tourmalines were added.
Please see my last photo, from page 203 in the definitive Fahrner book, "...Between Avantgarde and Tradition" by Hase-Schmundt, et al. The ring is pictured with four coral stones.
The condition is very good overall; it is missing one prong (but the stone is secure); there is a minuscule blemish on the corner of the onyx; and there is minor surface wear. In certain light, with scrutiny, you can see a light scuff mark on the face. I consider this normal wear for an old ring. I have priced it accordingly.
