the amulet is a good mf ammy with great life and crit hit dmg but not much else. due to crafted ammys having a min of 200 str, some with vit and the good ones have crit hit dmg ias and crit hit chance you'll still get some decent gold outta yours.. maybe 10m-50m depending. lookup the ah with similar stats since % life str and mf tend to be valuable.
as for the ring, its missing crit hit dmg, and ias, but an empty socket and decent stats all around make it worth a lil something. look it up in the ah and see what you can find.
