Here is a unique piece.  This ground plaque style tombstone is found in every real cemetery, so why not yours? 

It is simple, with no epitaph.  You can paint or carve your own!  This piece is cast in solid, durable polyurethane foam that is tinted dark gray.  This keeps any nicks or scratches virtually invisible.  This also allows you to carve your own epitaph without exposing bright white or yellow foam.

Approximate dimensions: H 5 1/2" x W 12" X L 9"
