The most famous was the Ring of Thrór: in Dwarven tradition it was said Celebrimbor gave the Ring to Durin III king of Durin's Folk before the Downfall of Eregion, but this seems unlikely as Celebrimbor was said to have yielded the Seven - all the Seven - to Sauron after torture.
The Dwarf Lords proved resistant to the malevolent magic of the rings, which could not even turn them invisible, as they are hard to tame, and the thoughts of their hearts are hidden. The rings, used only for the gaining of wealth, amplified their wearer's natural skills and desire for dominion which as a consequence, made them greedy and exceedingly rich; the Rings gave them the power to multiply whatever they mined. It is said that thanks to them the Seven Hoards were made. But also the Rings kindled greed and wrath in the Dwarves, bringing evils that in the long-term benefitted Sauron.
Four were swallowed or destroyed by Dragons, but Sauron succeeded in finding two. The last one was worn by Thráin II, but in T.A. 2845 he was imprisoned by Sauron in the dungeons of Dol Guldur, and the ring was taken from him.
 Portrayals in adaptations
1995-8: Middle-earth Collectible Card Game:
- Each of the seven rings has its own card (released in two versions, one for METW and one for MELE (some were released in the expansion MEAS): Dwarven Ring of Dwálin's Tribe, Dwarven Ring of Barin's Tribe, Dwarven Ring of Bávor's Tribe, Dwarven Ring of Thélor's Tribe, Dwarven Ring of Durin's Tribe, Dwarven Ring of Thrár's Tribe, and Dwarven Ring of Drúin's Tribe.
- The Seven appear in the introduction of the movie, worn by Dwarf kings. They are designed consistently to the general 'Dwarven' aesthetics of the movie, with angular, crystalline shapes. However nowhere in Tolkien's books is mentioned that the Seven were designed or made for the Dwarves.
2017: The Lord of the Rings Online:
- The Dwarf-rings consumed by dragons were not destroyed, but Sauron had those dragons imprisoned and tortured in an attempt to recover the Rings. The "Ring-drakes", as they were called, were "Hrímil Frost-heart", who consumed "Tínya" and the king of the Eastern "Zhélruka" dwarves who bore it; "Thostír the Rank", who consumed "Tulcya", the ring of another House in Rhûn; and "Fingar the Greedy", a Great Worm of Angband who consumed "Úrya" and "Vanya", the Rings of the Ered Luin kingdoms.
- Two other rings of the eastern Houses were reclaimed by Sauron: "Taurya" and "Sindya", the Ring of "Drása's Folk" (later dubbed "Stout-axes"), who called it "Manthríf". "Angya" was the name of the Ring of Durin, which was called "Handórm" by the Dwarves.
