This ring by Icelink has an interesting design: the centre rotates. It’s also set with (I believe) crystals. Also interesting is the website description: This stainless steel base Cross rotating ring is a true statement of IceLink’s creative vision. Reflected with the nostalgic prints it’s an emblem of the everlasting Armenian spirit.
I’m not sure what the Armenian connection is but … there you have it.
This sells for USD$120.
