Guessing you meant stonespeaker guardian from races of stone...nobody did simply because all classes like that can be found in an or class ability archetype.
Oread druid (Cave or Mountain archetype could work there) with the earth domain is a possibility or Suli Oracle with the Earth Mystery, just to give some examples.
Guess if the stone form is what you are after, probably better to look into the arcane with Sorcerer (Earth Bloodline or Shaitan Bloodline).
Just the basic that is crossing my head at the moment.
