Abstract

Natural diamonds are studied via confocal scanning fluorescent spectroscopy. Defects 523 and 794 nm have a number of similar features and are associated with one another. Features of their localization in the (111) planes of the individual growth pyramids testify to their postgrowth origin and are the result of plastic deformations. The structure of the defects presumably contains dislocations. The participation of other impurities in the structures of the defects is doubtful.
