Were do you get the stones from on RuneScape

if you are talking about the Christmas Quest than go either to the wizards tower or to a snow imp wearing a santa hat once your there click on him and ask if he can teleport you.
Once you are at the um place slide on the ice to get to a cave entrance (if you look on the minimap it's where all the people are that are not on the ice) go in now go to youtube and look up Runescape Christmas Quest Solution 2008 and do what he does.
