There are 12 stones. The diamond is embedded in one of the stones. Eleven of the stones weight the same, but the stone containing the jewel weighs either slightly more or slightly less than the others. Find the right stone and find whether it's heavier or lighter. You could use each of the three balance scales exactly once.
Can anyone help me out? My boyfriend and me are working on this one and haven't solved it yet.
