No Pokemon evolves with an everstone. In fact, an everstone negates the effects of evolution if you give it to a Pokemon to hold.

In Pokemon Blue, the Everstone can be obtained by defeating wild Geodudes and Gravelers in Rock Tunnel. These Pokemon have a 5% chance of holding an Everstone when encountered.
