Hi Keith, good question,
Granite and wood have different thermal conductivity.  Granite can absorb heat faster for a given temperature difference than wood can.  So the granite essentially sucks heat out of your hand faster than the wood.   Since your nerves are inside your hand, that means that the granite feels colder.
