One of the greatest rock collections in the world is here, and it's basically just a guy that started picking up rocks along the river when he was 12, and then got picky about the rocks looking cool as his collection grew, people started admiring the rocks, sending him cool rocks, offering him rare rocks, trading rocks from different parts of the world, offering him tours of major mines to find rocks etc. For 80 years. And he never went pro or did Geology, he made cabinets. Dude just loved cool rocks.

It's a very cool collection because it contains both very ordinary everyday minerals picked off the ground that look cool and deeply weird and hard to find shit.
