[Lindale]

Nice arguments everyone, for those pros and cons the silmaril-being-the-arkenstone. Although little Lindale's opinion is this:

‘And they knew that those jewels could not be found and brought together again, unless the world be broken and remade.’

Logically, an argument with an AND has to have all its premises true to make it valid. So... the Arkenstone can't be a Silmaril, it just isn't valid at least logically. Even if we take the argument that the world has been remade by the fall of Numenor.

I don't know how to put links, but you can Google it: pictures of our very own Mayon Volcano, a perfect cone. Unless I am heavily mistaken it is on the plains of Bicol region. So I can't think it's valid to assume that the Lonely mountain is an inactive volcano. Then again, how many volcanoes are there in Middle Earth? Mount Doom, if you will the Lonely Mountain, and what else? I've read somewhere back in high school earth science that if the earth had no volcanoes, then random parts of the land would have lava gushing upwards (I can't find the right words, but I hope you get it.)

And this. At some point in the past, the lonely mountain, if it is truly a volcano, should have erupted at least once in over five thousand years. After the fall of Beleriand Elves have lived in Rivendell, Lorien, Mirkwood, and Eriador, not to mention the mortals in Dale and the ancestors of the Rohirrim--do they not have any records of any eruptions, anyone noticing that smoke and lava running down the slopes? But if it isn't a volcano, then how did the Arkenstone come from the Lonely Mountain? Unless it was an extraterrestrial diamond (though it is unlikely): a meteor or an asteroid, one of Varda's stars (because where would it have come from anyway, but whether it is Varda's star or not is quite irrelevant), falls (remember that Eol got his black metal, what's it called again, from a meteorite) and thus delivers a carbonado kind of diamond.

So there. I might be really wrong about this, but... I disagree with the Lonely Mountain being a volcano and the Arkenstone being a Silmaril. Oh well. A fun thread!
