I have set an American mined turquoise cabochon in sterling and fine silver. The stone is framed in a hammered shadowbox setting which rests on a hammered split shank ring band. I have created this one-of-a-kind design by sawing, forming, soldering, and finishing the piece entirely by hand. The silver has been oxidized and polished to create a patina finish. This ring is US size 10.75 with an internal diameter of about 20.4mm.
