C., with both diamond and template being at the same temperature and the template being made of a metal or an alloy which dissolves the diamond carbon at the selected contact temperature and the diamond contact with the template is effected in vacuum, an atmosphere of inert gas or in an atmosphere of a gas which does not react with diamond at the contact temperature but reacts at such temperature with the diamond carbon dissolved in the metal or alloy.
