Need it have been Dwarves, in fact? I don't recall any innate difference between the lesser Rings of Power not made by Celebrimbor-that is, the Seven and the Nine. Could Sauron not have gifted human followers with the recovered Dwarven rings? The Mouth of Sauron, for instance, or Herumor of "the New Shadow"? (Herumor is a particularly interesting case as possession of a ring might just justify his being the same Herumor that lorded it over the Haradrim in the Second Age.)
