Is this copper?
Collected the rock on a riverside in Shizuoka, Japan. The speck circled in the last photo shines in the sun .

Found in a riverbed in Shizuoka. It looked interesting to say the least. When I was polishing, the slurry turned reddish so I knew some streaks were hematite. Apparently this is one of the few regions in the world where you can find schist like this. Cheers
