Webdiamond indicates that neither the surface dipole nor bulk quadrupole contribute to the NLO process. On the contrary, the NV color centers hosting near the surface region can break the inversion symmetry of diamond crystal lattice (Figure 1b), and it will become a potential source for the second-order NLO phenomena, such as SHG. http://www.phys.ttu.edu/~cmyles/Phys4309-5304/Lectures/Lecture01d.ppt

In crystallography, a centrosymmetric point group contains an inversion center as one of its symmetry elements. In such a point group, for every point (x, y, z) in the unit cell there is an indistinguishable point (-x, -y, -z). Such point groups are also said to have inversion symmetry.
