METHOD OF MAKING ARTICLES FROM DIAMONDS Russian patent published in 2015 - IPC B24B9/16 B28D5/00 

FIELD: process engineering.

SUBSTANCE: invention relates to diamond processing and may be used various industries. Processing is executed over natural facets of diamond to get the surfaces of 3D surface configuration including surfaces of 2^nd order: cylindrical, spherical, conical, parabolic etc. Natural morphology and relief of initial diamond are particle preserved at diamond surface. Various patterns are covered for formation of spherical surfaces like ball belt and spherical triangles. Formation of 2^nd order surfaces is performed with the help of full inner reflection angle. Formation of distorted images of light fluxes and inner defects is performed.

EFFECT: enhanced process performances, higher efficiency of diamond processing.
