Been pouring over my mineral handbook and can't quite figure out what the dark green rock embedded with quartz ore is. Anyone have an idea? Looks like it could make some cool jewelry if handled right. Appreciate any rockhounds chiming in.

It looks like it could be green aventurine which is a type of quartz.

Thank you guys for you analysis. Nothing flakes off..the shiny stuff is hard and appears to be tiny crystalized quartz facets. After looking up Mariposite images on Google I'd say it looks more like that than Aventurine, although certain Aventurine images have similarities as well. The green stuff and the quartz seem to group together in veins, patches and don't intermingle at a more granular level. Not sure that makes sense, but my gut says call it Mariposite until I can hand it to an expert. Thanks again...lots of fun trying to figure it out.

It looks like serpentinite, I posted a photo in the gallery from our last trip.
