This is a blue/green dichroic glass fused to a black opaque glass and made into a cabochon. After grinding the cabochon, the fine silver bezel cup fabricated and created to fit the cabochon/soldered and the fine silver ring shank soldered to the bezel cup. The glass cabochon was placed in the bezel cup and secured into the ring. All fabrication of the glass and the metalsmithing was done by me. Ring is a size 7.
