It looks like peacock copper...one of the copper iron sulfide family. Here's a link...you can look at some of the different varieties... http://mineral.galleries.com/minerals/sulfides/bornite/bornite.htm

Looks to be native copper to me with some oxidation minerals such as bornite. I have a piece that looks just like the one you have. It was collected in Michigan.

if it feels like Makeup its Valeriite, if its hard could be native coper,, I posted a picture of Valeriite on hard rock Forum and its natural feature includes Bornite ushually,, also found with Peacock Pyrites and sulfates.
