[TLOTR] Is the Arkenstone of Thrane the silmaril lost by Maedhros into the fiery pit?

Almost certainly not. The light of the Silmarils is the last remnant of pure untainted light in all of Arda and would be immediately recognizable as such; the Arkenstone is described as giving off "a little globe of pallid light". The Arkenstone was "cut and fashioned by the dwarves", but the Silmaril could not have been cut and would have needed no fashioning. The leaders of the Army of Valinor also predicted that "those jewels could not be found or brought together again unless the world be broken and remade", which could refer to the Downfall of Numenor but more likely refers to the much more relevant (to the Silmarils) Second Music of the Ainur, when the Silmarils will be used to recreate the Two Trees.
