I found this rock in the northern San Luis valley and was wondering what it is. I scratched it with a steel file and the metal rubbed off on the rock so I guess it’s at least 7 on the mohs? After tumbling it four weeks with a handful of other stones it lost quite a bit more material than the agates but was fairly shiny.
