I think I bought this in Utah a while ago.

Copper ore if nothing else - blue is also azurite as in your first posted pictures. Bass and probably tell you what the rest is - I like rocks that have oil in them - not these that just sit there until you destroy them.

nice pleochroism.

The bottom photo (if shown alone) looks like bornite (or enargite).  But the first two photos don't quite look right.  Possibly specular hematite.

Can you tell any more about the mineral.  What color is the unoxidized material?  Can you scratch it with a knife?  Can you melt it with a match or candle?  Does it have unique crystal shapes?

Ummm haha. I dont know what the color of it is unoxidized. And it doesn't scratch when you knife it. You can't melt it with fire. Here's the bottom of the rock.

Ah - I see the error of my ways.

In the first set of pictures I saw the "blue" when actually iy is the way the light reflects off the shinny hematite.

Sorry boss.
