Shock wave profiles of sapphire with eight crystallographic orientations с m, a, s, r, g, n and d -cut were measured at shock stresses in the range 15–20 GPa. Measured values of spall strength depend on direction of shock compression and peak shock stress. The largest spall strength values ~12–13 GPa were recorded for peak shock stress 16 GPa along the a-axis and the m-direction.
