Looks like the mineral Azurite.

Here's a simple way to tell.
All you need is a small amount of dilute (weak) hydrochloric acid. Azurite is a copper carbonate (not a copper oxide like some other user mentioned in one of your other pics ) so it should effervesce - basically fizz - when in contact with the acid. It's similar to how baking soda - sodium bicarbonate, fizzes to vinegar.

Even if you don't want to attempt this, I am pretty certain this is azurite. The other indicator is that your specimen also has a bit of green malachite (seen in one of your other images). Azurite is related in that it oxidizes to malachite over time, so that's further evidence that you have a nice blue azurite specimen.

Wow I would be scared to do that
but I did look at the original photo where it lists some of the.. I guess mineral compounds? It says Azurite, Malachite and Flourite next to azurite I can see it says blue copper, but under the other two the writing is cut off

Oh, there's s label with this piece? Yes, azurite's the blue stuff. The label would probably say then that the malachite is the green mineral. And fluorite...from the pictures you took, I can't see it, if it exists. But basically fluorite can come in a variety of colors, but the crystals are cubic. So if you see something probably glassy/lustrous and cubic in shape, that's probably your fluorite. Is there any?

from  what I see in the original, it looks like there are some big crystals that run along side the picture I believe I have the full picture in my gallery somewhere
