Here's my photo of the domed ring from the Master Muse tutorial, with a matte finish.

Here's a previous version, thinner, with a riveted shank and glossy finish.
The two rings both involved etched copper plus enamel. I also played some with plain enameled copper with more enamel painted on, like in these earrings.
I'm anxious to get home and experiment more, but right now my cast qualifies as a serious fire hazard, so I guess this will have to wait a few more weeks.
