Dvärgar var faktiskt naturligt resistenta mot Saurons skadliga effekter, kanske mer än än Hobbits.
Av Ringen om Makt och Tredje Ålder:
Sauron gathered into his hands all the remaining Rings of Power; and he dealt them out to the other peoples of Middle-earth, hoping thus to bring under his sway all those that desired secret power beyond the measure of their kind. Seven Rings he gave to the Dwarves; but to Men he gave nine, for Men proved in this matter as in others the readiest to his will. And all those rings that he governed he perverted, the more easily since he had a part in their making, and they were accursed, and they betrayed in the end all those that used them. The Dwarves indeed proved tough and hard to tame; they ill endure the domination of others, and the thoughts of their hearts are hard to fathom, nor can they be turned to shadows. They used their rings only for the getting of wealth; but wrath and an over-mastering greed of gold were kindled in their hearts, of which evil enough after came to the profit of Sauron.
LOTR bilaga A:
For the Dwarves had proved untameable by this means. The only power over them that the Rings wielded was to inflame their hearts with a greed of gold and precious things, so that if they lacked them all other good things seemed profitless, and they were filled with wrath and desire for vengeance on all who deprived them. But they were made from their beginning of a kind to resist most steadfastly any domination. Though they could be slain or broken, they could not be reduced to shadows enslaved to another will; and for the same reason their lives were not affected by any Ring, to live either longer or shorter because of it.
Förvandlas till skuggor som "vänder osynliga", den wraithform som leder så småningom till ringwraiths. Ringen, som en förlängning av Saurons makt, antyder detta, kan uppmana Gimli till ilska och utslagsåtgärder och till girighet, men kunde inte direkt påverka sitt sinne för att försvara sig. Bilbos band av dvärgar verkade lika opåverkad av ringen i deras närvaro.
