This was owned by my Grandma, so must date back to the late '50s or '60s. All I know is she got it in Arizona. Since I don't know the provenance of this particular piece, I cannot make a claim as to how or who made this. It appears to be a turquoise stone and sterling silver metal. It appears to be hand made.
The stone is approximately .75" diameter.
The cuff is 2.5" wide by 2 deep . The cuff being silver is somewhat adjustable. Please check the photos for all of the details of the setting and style
