Abstract

A method of growing a diamond crystal which comprises bombarding the diamond with a flux of carbon ions of sufficient energy to penetrate the diamond crystal and cause crystal growth which is at least predominantly internal, the temperature of the crystal being at least 400.degree. C. and less than the graphitization temperature, such that the diamond crystal structure is maintained during growth.
