Polymer Clay Rings
It doesn't cost a lot to make each finger fabulous when you start with inexpensive sterling-silver ring findings. The ring bases come to life with polymer-clay gems in colors and sizes that you can mix, match, and stack.

Ring findings –– gemless metal ring forms –– can act as both molds and clay cutters. It doesn't matter if the ring finding's cup is open or has a backing, but look for those with a crisp bezel edge to make a clean cut into the clay.
Ring findings with crisp bezel edges
Roll out a sheet of marbleized or solid-color clay as desired in the same thickness as the finding's bezel cup. Use this technique to condition and marbleize the clay.
Press ring into clay to cast and cut out the clay "gemstone." Then bake clay inside the ring.
Once the clay hardens, shave off any rough edges with a craft knife.
If clay pops out after baking, secure it with a drop of glue on the back of the ring cup or a fine line around the bezel's edge.
