This was made at school too. It is made from fine silver sheet. Learnt how to drill a hole in a stone. The stone is blue Onyx. The picture is bad because I had put away my home-made table top studio. We were selling our house and moving from MA to CA...one of the most heart breaking things I have experienced. I had lived in Shrewsbury, MA for 12 years...all of my married life. And got that house made ourselves (almost). It hurts even now to think of it.
Coming back to jewelry...the fine silver sheet was first roller printed, cut into circles, domed, soldered, and then the stone was set by soldering a silver wire post inside the hollow.
