I was referred to this sub and told to share my picture. I got most of these at local rock swaps.

You made me subscribe, so I guess these are cool rocks 😉

Do tell, how do you “swap rocks”? You’ll have to have something to swap first right?

Grab a rock off a sidewalk and go from there, like those "traded a pen up to a car" stories lol

Think rock flea markets put on by the local mineralogical clubs. I generally just swap cash.
