Is blue prosopite always clear?


#1

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


#2

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.
