A continuation: I found a reply by Gary where he states that the crest on the shield (and so perhaps the ring) belongs to an ancestor of his:
I always pictured the Ring of Gaxx looking like a D20 set into a ring.

I always imagined it to be an octagonal prism on a spindle rather than some magically rotating d8 though.
