Unlike the other Rings, the Three did not confer invisibility or bear a curse beyond their vulnerability to the One (as Sauron himself never laid hand on them), but the rings themselves were invisible when worn. Only a few, such as other Ring-bearers, could see them.
The Three are the only Rings of Power other than the One that Tolkien depicted in the narrative. Narya, the Ring of Fire, was set with a ruby; Nenya, the Ring of Water or Ring of Adamant, was of mithril and set with a "white stone", presumably a diamond (although never stated explicitly, the usage of the word "adamant", an old synonym, is strongly suggestive); and Vilya, the Ring of Air, and "mightiest of the Three", was of gold and set with a sapphire. They remained hidden, and their possessors were not revealed until the end of the Third Age.
Before the sack of Eregion, Celebrimbor gave Vilya and Narya to Gil-galad and Nenya to Galadriel. Gil-galad later gave Narya to Círdan, and gave Vilya to Elrond shortly before he died.▼

The Three remained hidden from Sauron and untouched by him, and during the Third Age after he lost the One they were used for the preservation and enhancement of the three remaining realms of the Eldar. Vilya was used by Elrond at Rivendell, Nenya by Galadriel at Lothlórien, and Narya at Mithlond by Círdan. When the Istari, or wizards, arrived about T.A. 1000, Círdan gave Narya to Gandalf, who bore it until the end of the Third Age.
