That kind of rock is called porphyry. Igneous rocks. You can grind and polish them into neat artifacts. Gary

Thanks that is cool. I will tumble them and see how it goes.

Dark one with light colored inclusions is basalt with plagioclase phenocrysts (porphyry)
Dark one with green inclusions is amygdoloidal basalt with what looks like celadonite
