please show samples of misty carrera quartz for kitchen countertops
I would say smoky quartz is a very good guess. I can see curved fractures which would support quartz as an identification.
Who knows? It could be quartz, but it's a little hard to say when the material is ground down. It could just as well be a chalcedony. The only certain thing is that it has no magical powers, if that's what you're thinking. . When you accidentally ask multiple questions, the polite thing to do is to use the Edit button to delete the extraneous one(s) before someone answers them. (After they are answered, questions can't be deleted.) . .
