The Rings Of The Raingwraith Where Made Of What?

Q: I was wandering what where the ring of the rigwraith where made of ? I think I rememeber reading they were made of silver and where plain like the one ring but made of silver !

A:All of the Great Rings but the One apparently had a gemstone of some sort set into them. The lesser rings were plain like the One and thus Gandalf long assumed that Bilbo's ring was of that sort. The Great Rings of the Nine would thus have had gemstones. What metal they might be made of is unknown, but I would guess that most would be gold. Silver would seem (to me) unlikely as JRRT indicated that silver was largely free of Morgoth's taint, though individual items of silver could certainly be exceptions to this. Still, given choice of substance I think Sauron would have instructed the elves in skills for fashioning things of gold, a substance more wholly infused with Morgoth's power. At the Council of Elrond, Gandalf quotes Saruman: '"The Nine, the Seven, and the Three," he said, "had each their proper gem. Not so the One. It was round and unadorned, as it were one of the lesser rings; but its maker set marks upon it that the skilled, maybe, could still see and read."' So every Great Ring except Sauron's One Ring had a gem stone. I went ferreting, and was able to turn up some details about the makeup of the Three and the Seven but not the Nine. We know that Sauron's Ring was plain gold; there are many, many references to this in LotR. We are given mixed signals about Galadriel's ring (the Ring of Adamant, one of the Three). First, in "The Mirror of Galadriel", we are encouraged to think of it as gold gold: "it glittered like polished gold overlaid with silver light, and a white stone in it twinkled". But then later, in "The Grey Havens", we read "On her finger was Nenya, the ring wrought of mithril". The same paragraph tells us that Elrond's ring was gold, and later in the chapter we read that the stone of Gandalf's (originally Cirdan's) ring was "red as fire"; but I've been unable to discover anything about the metal of that ring. In "Of the Rings of Power and the Third Age" in /Sil/ we read "It is

said that the foundation of each of the Seven Hoards of the Dwarf-kings of old was a golden ring; ...". I've been unable to discover any statement of what the Nine were made of. In a recent thread I maintained, based on texts that I quoted there, that there was no difference between the Seven and the Nine: that Sauron just got 16 Great Rings out of his war with the Elves of Eregion and of those 16 he gave 7 to Dwarves and 9 to Men. If that's correct (and I do not think I established it as definitely true), then the Nine would also be golden rings. But we do definitely know that each of them had a gem; see Gandalf's words at the Council of Elrond (above).
