Iron pyrite on schist or slate. It could also be chalcopyrite.

Maybe, but a magnet didn't attract it. Here's a sharper view of a nice piece I extracted from a black stone brought
from a quarry.

Iron pyrite isn't magnetic. Here's a crystal cluster of pyrite.

Minor point, very minor..it is magnetic, in cases, just not with a "regular" magnet normally. I bought a reeeeeeally powerful magnet a few years ago for magnet fishing and naturally crossed interests and have detected the magnetic field of many things I never really thought of as
magnetic (even what were previously "non-magnetic" hematite specimens. Love the color (likely more iron/sulfides) in the sample provided, plus it's shape...seriously a good specimen!
