it's either nephrite, jadeite, or slag in my opinion. Where did you find it, state, province, etc.?

Edit, it's not slag on closer exam. Still going with nephrite or jadeite though

The black spots are due to the space travel it endured before finally reaching Earth.
You have a chunk of Kryptonite.

I agree with PikesPeakCharlie. The black spots are also indicative of it being malachite as well.

Here is a pic of the inside after being cut. I agree it looks like malachite, but I don't see the layering patterns like most malachite.

A good place to start would be to check the hardness and streak color

I scratched it with quartz. It only left a white streak. but It didn't scratch it. The streak color is turquoise color.

The streak color alone would seem to eliminate jadeite & nephrite. Jade: A beautiful and durable material of nephrite or jadeite

The hardness by itself would seem to eliminate malachite. Malachite: Uses and properties of the mineral and gemstone

What other mineral could it be?
