The Dwarves: The second age (p3)

Durin III was in power around the year 1600 of the Second Age. He was gifted with the seventh and most powerful of the Dwarven Rings of Power. It was the Elven smith Celebrimbor and not Sauron who gave him the ring. The rings of power did not have the effects that Sauron had intended, possibly because Aulë had made the Dwarves especially resistant to evil domination. The only apparent effect of the Dwarven rings was that the Dwarves became more greedy with gold lust, but they were not turned into wraiths like men. Sauron tried to recover the rings. Two he reclaimed fairly soon and four ended up in dragon hoards. Sauron did not reclaim the ring of Durin until the 2845th year of the Third Age when he captured Thráin II.

Of the Dwarves, few fought upon either side; but the kindred of Durin of Moria fought against Sauron.
