An inertial frame of reference, of course.

If the rocks are in an otherwise empty universe with no other massive objects to relate to, then I guess you could use light as a frame of reference. If a laser is placed on one rock and aimed at a target on the other rock, the light would miss the target if the rocks are rotating. This is basically using a simple form of a Sagnac device to detect rotation.
