<p>@Barhir if you read my response you'd know that I'm not suggesting that "all gems" have power. The silmarils are far stronger than my proposed idea, things don't need a prophecy from mandos, or any valar, to have power. There was no prophecy to making rings of power, yet they made them nonetheless, many of which probably had gemstones.

</p><p>That's what <i>he</i> said about the palantir, yes, but just because he said it doesn't make it right. I think everyone understands they were Crystal balls, are you seriously going to contend they were something akin to marble? "They were perfect spheres, appearing to be made of solid glass or deep black crystal."

You are entitled to your opinion, I disagree. But I thank you for not being, shall we say, so hostile.
