Hello all, new member and happy to begin sharing what I find on here . My first question is in regards to this chunk of "native copper" I got from an off beat shop and it looks to be an unusual example of native copper in its matrix. The copper appears to be very much mixed in with the quartz. And all the quartz crystals are aligned, I am certain it is a natural occurrence just a strange one. Has anyone seen anything like This?

This form of copper is fairly common, and there are several localities near me in Pennsylvania and New Jersey that produce copper specimens like yours. I believe it's from hydrothermal solution depositing the copper mineralization in cracks within the original quartz deposits. The localities that I mentioned in PA/NJ also have similar copper mineralization in siltstone and greenstone in addition to quartz as well.
