§ Of the Rings of Power and the Third Age The Silmarillion

Many treasures and great heirlooms of virtue and wonder the Exiles had brought from Númenor; and of these the most renowned were the Seven Stones and the White Tree. The White Tree was grown from the fruit of Nimloth the Fair that stood in the courts of the Bang at Armenelos in Númenor, ere Sauron burned it; and Nimloth was in its turn descended from the Tree of Tirion, that was an image of the Eldest of Trees, White Telperion which Yavanna caused to grow in the land of the Valar. The Tree, memorial of the Eldar and of the light of Valinor, was planted in Minas Ithil before the house of Isildur, since he it was that had saved the fruit from destruction; but the Stones were divided.
