What are the Silmarils, and what relevance do they hold in The Lord of the Rings: The Rings of Power and the rest of Tolkien’s story? The Silmarils are seldom mentioned during Frodo’s quest in The Lord of the Rings, but within the wider context of J.R.R. Tolkien’s legendarium, their importance is rivaled only by Sauron’s One Ring. Amazon’s The Rings of Power has dropped a couple of passing Silmaril references but hasn’t incorporated them as much as it could have. Still, the Silmarils’ importance is felt in the reverence shown toward them during their rare mentions in Rings of Power.
