These are “skirt rings” that are to be part of a fantasy costume.
Don’t feel dumb, I didn’t know what a “skirt ring” was either.
They were a commissioned custom order for Blizzard Entertainment. A video game company that produces online games such as World of Warcraft and the Diablo series.
One of the joys as a metal artist, is that I never know who is going to contact me or what creative adventure is around the corner.
