A problem due to Martin Labar is to find a 3x3 magic square with 9 distinct perfect square entries or prove that such a magic square cannot exist. In this paper, I assume that such a magic square exists and show that the entries must have certain properties. This is accomplished using unique factorization in two different finite extensions of Z. One property that is proven
