Not specifically. You can battle pets in the family that you want the stones but if you want stones and can wait a bit, go the daily route. For all the pets I actually caught myself (as in, no store or traded pets), less then ten were actually rare when I got them. 99.9% of my rares came from the stones I got in the daily sacks and now that I've stoned all my battle pets (it seems wrong to stone the non-battle pet kind), I still have way more stones than I know what to do with. I think my stone carrier has at least 10 of each kind (many more of the kind I got a great deal of and of which have less pets in general.)
When you get three of a certain kind, you can turn them in for an unmarked stone, so that helps too. It's not like OMGNAO stones but if you're patient, you'll get there.
