Ice grain boundary energies  relative to the free surface energy were determined by studying the topographic details revealed by plastic replicas of the ice grain boundary groove-free surface with a Laser Confocal 3D Microscope. The samples analyzed were high purity ice bicrystals, with  tilt grain boundaries, annealed at -18o C. Values obtained of were analyzed using coincidence site lattice (CSL) theory. Significant correspondence was found between the  values and the planar density G of coincident sites on the interface plane. The results show that  depend on the GB symmetry and could be up to one order of magnitude different.
