The voice (stone) stands firm only because of the good support. In similar way does a beautiful singing voice. The piece in this picture is one of the first cabochon stone settings I did. The actual supporting ring made the stone setting a bit hard. I had to balance the whole piece by the supporting beams when applying pressure on the silver rim around the stone.

Gemstone in the picture is rose quartz cabochon. Ask for other stone options.
The pendant is sterling silver (925).
