The Silmarils (Quenya Silmarilli) were three gems of immense might and beauty.
The gems were named for and crafted of the hard crystalline substance silima, which Feanor had devised, as their shell; in their heart burnt some of the Light of Valinor from the Two Trees. Their exact nature and manner of making the Silmarils were known only to Fëanor, and none other succeeded in making gems of comparable greatness and beauty. Varda hallowed the Silmarils so that no mortal or evil hands were allowed to touch them without being burned and withered. 
The Silmarils were tainted by arrogance and lust by anyone who desired them, starting with Morgoth, then Feanor. As the Doom of Mandos proclaimed, it resulted in evil ends, such as the Fall of the Noldor, the [[Oath of Feanor, Kinslayings and the destruction of Doriath.
Feanor wore the jewels at festivals and the Eldar admired them. Corrupted by the lies of Melkor, Feanor started to lock them away, and became greedy for them. After Fëanor was exiled to Formenos, the Silmarils were stored in a chamber of iron.
Together with Ungoliant, Melkor destroyed the Two Trees. The Silmarils now contained all the remaining light of the Two Trees. Therefore the Valar entreated Fëanor to give up the Silmarils so they could restore the Trees, but he refused.
Then news came: Melkor had killed Fëanor's father Finwë, the High King of the Ñoldor, and stolen all the gems, including the Silmarils. After this deed Melkor fled to the northlands of Middle-earth, where his ancient fortresses were. Ungoliant even quarreled with him as she wanted to devour the Silmarils. Melkor, now named Morgoth by Fëanor, set the Silmarils in his crown even though their holy light burnt his hands were burnt and ceaselessly tormented him.
Fëanor was furious at Melkor and at the Valar's perceived desire to take the gems for their own purposes, and, swearing that he and his sons would not rest until the Silmarils were recovered, he led the Ñoldor back to Middle-earth. His flight, led to no end of grief for the Elves and eventually for the Men of Middle-earth. Five major battles were fought in Beleriand, but ultimately the Ñoldor failed.
King Thingol, wishing to dispose Beren, tasked him to fetch one for the hand of his daughter. Impelled by his love for Lúthien, Beren recovered one through great peril and loss, only to be swallowed by Carcharoth, until the Wolf was slain in the Hunting of the Wolf. The Silmaril thus was delivered to Thingol, fulfilling his Quest.
Doom of the Noldor
Instead of giving it to the Sons of Feanor, Thingol had the gem stored inside the dwarven pendant Nauglamir by the Dwarves of Nogrod, who however also coveted the jewel and killed Thingol. Doriath was ruined and Menegroth were sacked by the Dwarves. The Nauglamir was recovered by Beren in Tol Galen, and Luthien wore it until her second death, becoming the fairest vision west of the Sea. Pursuing the Silmaril, the sons of Feanor, destroyed Menegroth and the Havens of Sirion.
The Silmaril however ended up in the hands of Eärendil, and its light guided him through the Shadowy Seas and found his way to Valinor. It was shown to the Valar as a token of repentance. The Valar then set this Silmaril as a Star and worn on his brow.
The other two gems remained in Morgoth's hands, and were taken from him only at the end of the War of Wrath. However, soon afterwards, they were stolen by Fëanor's two surviving sons Maedhros and Maglor. The jewels burned their hands, in refusal of their rights of possession, as they were corrupted by their deeds. In agony, Maedhros threw himself and his Silmaril into a fiery pit, and Maglor threw his into the sea. Thus the Silmarils remained in all three elements of Arda -- in the sky, soil and water --, fulfilling the prophecy made by Mandos shortly after the making of the gems. 
It is said that Feampr will return only for Dagor Dagorath, following Melkor's final return, and defeat him to reclaim his beloved Silmarils. The world will be changed and he will surrender them to Yavanna who will break them and with their light she will revive the Two Trees. The Pelóri Mountains will be flattened and the light of the Two Trees will fill Arda again in a new age of eternal bliss.
The proper Quenya plural form is Silmarilli', Silmarils being an Anglicised name.
In the Etymologies appears the Noldorin name Silevril, being related to Quenya Silmaril. Tolkien appears to have retained the Noldorin form in Sindarin, since the name Pennas Silevril (apparently the Sindarin translation of Quenya Quenta Silmarillion) is used in later manuscripts.
In Aelfwine's Old English translations, the name Silmaril is rendered phonetically as Sigelmaerels. As noted by Christopher Tolkien it is composed of OE sigel = sun, jewel, maerels = 'rope', actually referring to the Nauglamir.
