need help identifying this one. It is a brown rock with greenish blue on it. Came in a baggie with some turquoise I bought at a yard sale, but wasn't sure if that is correct. Please help if you can.
Hard to tell - but definitely looks like a secondary copper mineral. See if you can post a large, more zoomed-in picture.
this one is closer. Will also add one of another side
I'm wandering about the blue color;
is it like azurite blue? Or more like a turquoise?
I think I even see some green.
Just maybe (and I say maybe) a rough azurite malachite?
its more of a turquoise color than blue
Wrong green blue for copper
