When placed in the fire, the one ring displays the inscription:
Three Rings for the Elven-kings under the sky,
Seven for the Dwarf-lords in their halls of stone,
Nine for Mortal Men doomed to die,
One for the Dark Lord on his dark throne
In the Land of Mordor where the Shadows lie.
One Ring to rule them all, One Ring to find them ...
Thus the one ring was owned originally by Sauron, the three elven rings by the elves, seven by the dwarves, and nine by mortal men.
Several of the rings are specifically mentioned in “The Fellowship of the Rings.” Of the elven rings, Galadriel wears it in Lothlórien. Narya is worn by Círdan Lord of the Havens and then by Gandalf. Vilya was worn by Elrond, and uses it to maintain Rivendell. All of the nine and four of the seven were held by Sauron, Three of the dwarven rings were destroyed by dragons.
