I think what you're seeing is actually 2 shadows, because if you look, you'll see a different shadow line near the nose. Looking closer, it almost looks like the nose shadow passed through the face to be seen on the neck. It could also be a shadow from hair. The end result is there is a nose shaped shadow at about 4:30 (clock face) on her neck.
