I am going to go with azurite with chrysocolla. Bisbee is probably a correct location. Nice piece! Here is a similar piece, yours is nicer. www.ebay.com/itm/202571005601

I can see a little Malachite in there, too. Pretty rock!

Beautiful specimen! I had one VERY similar and was told it was Malachite/Azurite. I love the colors...and it's SUPER soft!

That’s what I see in this too: the azurite, lighter blue chrysocolla, and a little malachite. The lime greenish material throws me off though. And yes Jason it’s pretty soft. I’m not doing anything lapidary wise with this till way down the road, if at all. It does have the cut off section so someone somewhere worked at least a piece of it.

Yeah I like mine better but it’s a bit smaller. It was a lot cheaper too! The guy had another one that was a little smaller for 20 bucks, I probably should have got that one too. It had small black specks mixed in with it.

I see mainly azurite and malachite, which are often found together as azurite converts in to malachite.
The lighter could be a number of things such as rosasite. Without some tests it is impossible to say for sure.

It would think it very difficult to be sure Shattuckite (Cu5(SiO3)4(OH)2, H=3.5) or Azurite (Cu3(CO3)2(OH)2, H=3.5 - 4) from an image. I have cut several Shattuckite and it was much harder than the 3.5 on mohs listed in Wikipedia. The round spheres in image 1 & 3 make me say Azurite. So most likely as others have already said, Azurite and Malachite. Shattuckite is not as intense blue as Azurite. Variations from computer to computer make subtle shading differences hard to tell for sure. Wikipedia says, "Commonly spherulitic aggregates of acicular crystals" for what that means take a look at the image on the Shattuckite wiki page.
