In parts of Michigan, you can pick up a fairly ordinary chunk of limestone & with some polishing, reveal a coral formation that was laid down when this area was a tropical sea in the Devonian, 350 MYA. These are Petoskey stones, the state stone of Michigan.

The same rock before and after lapidary polishing.  It's held in a human hand in both instances.  On the left, a plain looking white limestone lump, roughly triangular.  It has a few pits.  On the right, a polished and shiny lump of coral in very roughly hexagonal pattern, a darker grey-brown, with lighter divisions and radiating pattern in each cell.
