Bronze sheet, cut, shaped and hammered by hand with a copper wire flush bezel surrounded by an argentium silver wire circle. In the center is a lovely little 6mm pale blue Brazilian aquamarine cabochon. The metals are fused with bronze solder. Argentium fuses to copper beautifully all on its own. Before the stone was affixed, I divoted the shank with a phanishing hammer to diminish the pressure of keeping a high bright shine on the ring. The ring measures 9.25 on the mandrel. The band is 1/2 inch wide. Will be sent with a small polishing cloth.
