I have set a genuine turquoise cabochon in sterling and fine silver. The round stone is framed by a smooth triangular shadowbox setting. 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 8.25 as sized on a standard US ring sizer. Turquoise: 14mm Be sure to see all photos and video for size and color reference.
