A few of the rings I have made.
Nothing special here; just gluing on and waiting.
The ring with the white middle was a button. It had a loop on the back so I cut that off before gluing it on the ring base.
The silver grecian-looking ring was a clip on earring. I just snapped off the clip bit.
The cameo was from a 'make your own cameo bracelet' kit and the green one is just a flat back crystal.
