<p>Well gems are, well, gems, and clearly that refers to the rocks. So I thought all gems were actual gemstones. And unlike bismuth, which is not only a metal, but a metal element (not an alloy, which is a combination of metals), pearls are actually made up of a variety of materials, and have gem-like properties. It atleast makes sense to classify pearls as gems, especially when you consider the fact that their considered objects as opposed to people by gems like peridot (or atleast, she used to). But bismuth is just, well, kind of random. Iron is a metal element too, and so is gold, silver, and a whole lot of other metals. Are they considered gems in this world too? I hope not. That's stretching the term "gem" far past what it should refer to.
