This beautiful 1930s black onyx filigree ring is stunning.  With a curved, almost oval shaped surface, this black onyx contrasts beautifully with the white gold filigree mounting.  The black onyx is held in place by six elegantly engraved ring prongs.  At the center of the black onyx, is a small accent diamond framed by a white gold diamond design.  The lovely openwork filigree shows inverted hearts and a linear pattern.   This 1930s Art Deco black onyx white gold filigree ring is made in 14kt ( 585 ) white gold.
