You can Momo just failed her spellcraft checks. Well in a sense she did. To identify a magic item it's 15+ the caster level of the item. Ioun stones have a caster level of 12 so the DC is 27. However to tell if a item is a curse item you have to beat the DC of the item it's pretending to be by 10, so a DC of 37. She only got 35's while identifying those. Therefore she identified them to be regular Ioun stones.<br/><br/>Anyway not the end of the world. Remove Curse, 3rd level divine spell, 4th level arcane. Not that hard to acquire as 7th level characters.  :P
