PROCEDURE FOR PRODUCTION OF DIAMONDS OF FANTASY YELLOW AND BLACK COLOUR Russian patent published in 2011 - IPC C30B33/04 C30B29/04 C01B31/06 A44C17/00

Abstract RU 2434977 C1

FIELD: metallurgy.

SUBSTANCE: procedure consists in ion-energy-beam processing diamonds with high power ion beam of inert chemical element of helium with dose of radiation within range from 0.2×10¹⁶ to 2.0×10¹⁷ ion/cm² eliminating successive thermal annealing.

EFFECT: production of amber-yellow and black colour of diamond resistant to external factors at significant reduction of material and time expenditures of process of diamond upgrading.
