Introduction—Opinion is divided as to the true crystal symmetry of diamond. Some authors, notably Fersman and Goldschmidt, who have investigated its morphological and etch characters, consider it is always hemihedral, whilst others, by the same methods, have obtained results which indicate holohedrism. Early work by A. Artom showed that it was seldom piezo-electric, but more frequently pyro-electric. Van der Veen also carried out avery thorough investigation and found no piezo- or
