An odd mystery rock from Shetland

Any readers have any idea what this strange rock is? It’s got wild patterns! These samples were in the garden of a local rockhound in Lerwick; I have zero idea what the mineralogy is; I was just stunned by the “scale-like” pattern of gray and pink. I’d be eager to hear your ideas what this might be. Thanks very much in advance!
