Here's how to make rings
This is how I make my rings. I used 16 gauge silvered wire. Wrapping it around ring mandrel, or what ever you can find around the house, 3 times. The wire is quite soft and easy to bend. You can use Sterling silver wire if you want. It probably looks better but a lot more expensive. Curl both ends up and tie the top part with smaller gauge wire. Roll a thumb size ball from Black clay and push it down to the ring. With a pea-size ball of clay, cover the back of the ring. Smooth and reshape the ball. Let the clay sit for a while to firm up. Decorated it with what ever you want. Have fun!
