14kt Green Onyx Ring

Art deco 14kt two-tone green onyx ring. Green onyx has a small diamond set in the center with a yellow gold bezel and then accented with white gold surrounding and extending halfway down the sides. Truly unique piece.  The ring is a size 6 1/4 and measures slighty longer than 3/4 of an inch from tip to tip. 
Circa dated 1925
