This is a piece that came in my prize box from Beefjello. I am assuming it comes from his home state of Arizona. It looks to be a mass of Chalcedony mixed with a very odd crystal formation. The black angular crystals are well defined(about the size of a dime) and protrude outward and are highly reflective. The closest thing that I can resemble them to is how a rough sapphire or ruby appears with its thinly layered sheen. These crystals are mostly black, but in some spots they also fade to grey or white in the same formation. Any ideas as to what they might be - and would it be possible to safely remove them and have them done as, say, faceted gems? Thanks for any information.

I see some very simular rock in the Mitchell area. Its a mix of crystal and Fieldspar. I see in the last pic what may be a reflection or is it a flash like a fieldspar???

That is the reflective surface flash of the crystal itself. Each one has a 5-6 sided shape and each side has that same reflective look.

Hard to tell without a hardness value- But I have to lean towards a feldspar also- Feldspar and quartz would be my best guess-
