The first due to a childhood obsession. The second for its properties. They may not be true, but i believe in the placebo effect and i can use all the stress relief i get.1

Limiting it to rocks that I've easily found just laying around, I always liked obsidian, because of the smooth glassy black surface. I also liked finding pumice when I was a kid, because a rock floating rock is fascinating for a kid.
I also like sandstone and basic quartz of many colors. If fossils count, I like fossils. Where I live I can go out and pick up fossils any time I want. They are mostly small sea plants, small twigs, and a few small low life forms. Sorry, no dinosaur bones around here :) not that I know of anyway. (but I've been to Dinosaur National Monument in Colorado)
And can't forget petrified wood. Petrified Forest in Arizona is really cool. There are petrified logs in other places in the US also, like Yellowstone for example.
Not the best example. but...
