Didn't the gem on the ring have an impossible number of facets *looks in DMG* -- yeah it was 9-sided with all sides identical*.
*it doesn't say they're identiical, but they can't be told apart by any examination though there is apparently only a single axis of rotatation since once you know where on facet is, you know where they all are.
