The Seven Dwarf-rings were the Rings of Power given to seven Dwarf Lords by Sauron in the guise of Annatar. Apparently the Lords were the Kings of the Seven Houses, as Gandalf mentions that the Rings were given to the "Dwarf-kings".
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. The rings amplified their wearer's natural skills and desire of dominion which as a consequence, they became greedy and exceedingly rich; the Rings gave them the power to multiply whatever they mined.
Angered by his failure, Sauron tried to gather the rings back to him. He succeed in finding two, while four others were swallowed or destroyed by Dragons. The third ring Sauron obtained was taken from Thráin II in T.A. 2845 while he was imprisoned by Sauron in the dungeons of Dol Guldur. Gandalf arrived too late and only got the key and the Thór's map to the secret entrance of the Lonely Mountain from Thráin.
