Bruneau jasper small, from Idaho, is sold in small sizes, mainly for tumbling but with a little effort, most can be slabbed for cabs. (Stock 510) This rare material is in shades of brownish red and tans. Bruneau jasper is no longer being mined due to being in a preserve, and is only found one place in the world. See Assorted Lapidary Tips for a tip on slabbing small stones easily.
