What gemstones and fossils can naturally be found in the great Smoky Mountains?

Every time I try to look it up all i see are ads for gem mines that are mostly seeded. What are the natural gemstones and fossils found there? The first three results do not include specific gemstones and fossils found in the area, just the type of rock that is found there.

Maybe your Google is different from mine.
