It looks like a typical ultra mafic rock. Like diabase maybe. The white could be plagioclae feldspar and the dark green pyroxene. Fine grained igneous rocks like that were used by Indians to make celts and axes. It’s tough and can take a beating. What is the source of this rock?

bought it from a private collection and have asked him where the stone is from. but i have yet to get the answer. P.S. how can you tell the difference between a weathered eucrite and a weathered possible diabase??

UPDATE: The rock has been found in a pile of rocks on a farmers field in Friesland (Netherlands). What is realy unusual is that the rock has several windows ground into the stone and the finder of the rock didn't do that. So an old rock from a field probebly glacial with ground windows into the rock???? And those real grind windows and not scars from a glacier.
