Help identifying the green bands in quartz

I'm guessing the green bands in this rock I found high banking is crystacola, but am not 100%. Can anyone confirm this?

I'm guessing you found it in AZ by your location tag. There is some possibility it may be chrysocolla though there are no blue's present. More likely its malachite inclusions in an agate or chalcedony base. AZ is good for alot of copper minerals and various forms of malachite, azurite and turquoise are pretty abundant. Looks like it has good hardness so it might be worth polishing up.
