The highest possible resistance you can have on a ring is 95%, abnormal resistance only ranges up to 75% though.
Rebirthed characters should also have their rebirth rings on at all costs. It's an extremely good ring.
There is also 3 different skills that reduce your resistances, this can hurt in PvP.
Other rings that is extremely useful is potion recovery speed (increases the speed that you recover health), transparency (makes you semi-invisible to enemies).
All abnormal resistances can also be found on 2 other unique items, earrings and circlets. If you can get prefixes on these items they will be extremely good.
Also dont forget that other resistances can be found on various different unique items. It's always a very good stat to have.
If you have any further questions about resistances, pm me ingame (:
