A comprehensive analysis of modern methods used for diamond identification has been carried out. It is shown that high thermal conductivity cannot unambiguously testify to the authenticity of a diamond, since synthetic imitations of silicon carbide have recently appeared. It is shown that electrical methods of gemstone diagnostics are promising but not yet sufficiently developed. A set of innovative electrocalcium methods for diamond identification is proposed. Techniques for measuring high resistivity, dielectric permittivity and surface potentials, which can be used in the procedure of diamond identification, are developed. An operational model has been tested in the study of new and traditional dielectric materials. The possibility of detecting differences in electrical and physical properties of externally identical materials using this method is shown.
