Tolkien was uncertain whether there were one or two jewels named The Elessar. The first was made by Enerdhil, jewel-smith of Gondolin for Idril who gave it to her son Earendil, thus Aragorn insisting that Bilbo includes a green stone in his song at Rivendell, the second was made for Galadriel by Celebrimbor. He hesitated as to whether the jewel which came to Aragorn was the first one or the second, or whether they were the same jewel. The story of Gandalf bringing it from Yavanna is one version, and the other descends from Galadriel to Celebrian and on to Aragorn from Arwen (as a bridal gift, see Laws and Customs Among The Eldar.Wielding the Elessar all things grew fair about Galadriel, until the coming of the Shadow in the Forest. Galadriel gave the Elessar to Celebrian because its power was deemed to be lesser than Nenya, which she received from Celebrimbor later.


As a note, Peter Jackson gets this absolutely wrong. The White jewel Aragorn wears is the one that is supposed to be given to Frodo by Arwen, Aragorn should have a green jewel.
