I'm kinda stumped by this. What is it?

What is this rock?
I have this rock. But what I don’t have is an idea of what it is.

It looks almost as if t is turquoise, and given that it is from Arizona I Beleive that there is a chance that it is.

There look to be other minerals interlaced into what I think is turquoise.

It would really rock if you guys can help me out!

I don't believe it's turquoise. It may be chrysoprase, a green chalcedony, or agate. Found in Arizona, Cal., and Oregon.

Turquoise is a blue mineral of copper. A related mineral Malachite is green. Chrysophrase, a chalcedony noted by Kray, derives its coloration from nickle. Arizona is rich in copper minerals and finds such as yours are pretty easy to come across. Neat stuff~ I have a bunch of it As to what you have there its to granular for chalcedony so its primarily large grained semi-crystalline quartz and I feel that there is malachite laced thru it via inclusions and in the fractures between the grains. The effect is what you see~ a nice translucent green.

first thing that came to mind was Amazonite but I don't know about any locales in Arizona, plus I don't thing the cleavage matches

 

[CharlesFulker]

Would it be worth breaking it open? Will it look better in the inside?

Not likely. Would recommend against it strongly.

If you know anyone with a lapidary saw, cutting it might be a good idea. But trying to break it will not work out well.

There are feldspars in AZ but I am unaware of an localities for Amazonite. It has a pretty distinct look and cleavage. I agree a cut would be a better idea for a look inside.
