Last week our rock work was completed and I looking for opinions. Should I be worried about what appears to be color leeching out of this stone? I'm no geologist but it appears to be rust. Maybe this particular piece has some iron in it. It it called Three Rivers Flagstone.

Thanks

You are right that it is the iron in the stone 'rusting' that's what gives it such a great color. But -- WOW -- that's a lot of streaking on the gunnite in just 1 week! I'd have that piece removed and replaced unless you are thinking about dark plaster.
