Answer 2

in pokemon diamond, moon stones are really rare to find underground but you should try digging from place to place. moon stones are really rare, so try to go underground digging everyday. and a guy hiker do not sell stones underground. he sells traps and furniture for your underground base.  there is no exact place to get a moon stone. sorry.............and hikers will give you spheres if you sell your treasures like the moon stone or fossils to him.
