Interesting material types for fantasy resources/macguffins other than crystals or metals?

You know the trope: an epic fantasy world with magic materials that have strange properties or give people superpowers or what have you. It seems half of the time, this material is a type of crystal with some kind of electric power, and the other half of the time it's a type of metal that's basically steel, but stronger or something. The main examples that come to mind are Marvel, where you have the Soul Stones, Adamantium, and Vibranium.

Are there any other cool types of materials to use for this type of resource? Like maybe an obscure type of material that certain scientists study, but the general public doesn't know much about?
