Fëanor, at the pinnacle of his might, "in the greatest of his achievements, captured the light of the Two Trees to make the three Silmarils, also called the Great Jewels, though they were not mere glittering stones, they were alive, imperishable, and sacred."
Even the Valar, including Aulë, could not copy them. In fact, Fëanor himself could not copy them, as part of his essence went into their making. Their worth, in Tolkien's universe, was close to infinite, even to the Valar, as they were unique and irreplaceable. So "Varda hallowed the Silmarils so that thereafter no mortal flesh, nor hands unclean, nor anything of evil will might touch them, for it would be scorched and withered."
Fëanor prized the Silmarils above all else, and grew increasingly suspicious that the Valar and other Eldar coveted them. Melkor, recently released from three ages of imprisonment in the Halls of Mandos and now residing in Valinor, saw in this suspicion an opportunity to sow dissension among the Noldor. Fëanor did not trust Melkor and refused to communicate with him, but was still caught in the evil Ainu's plot.
