Is blue prosopite always clear?

Is blue prosopite always clear or can it be spider webbed? Can it be green? Can it have dendrites?

Blue prosopite can have dark matrix in it. I found this pic that shows some dark material, but I haven’t found any pics or information on anything like the spiderweb veining shown in your pics. It may be possible.

Prosopite can be green. Our gem listing notes a source in Utah.

I suppose it’s also possible for dark matrix to create tree-like shapes, but I didn’t find any pics that show it.

If you’re trying to differentiate prosopite from turquoise, note they have very different refractive indices.
