Comparative analysis of Uralian, Anabar and Brazilian diamonds by infrared spectrometry method
Uralian, Anabar, and Brazilian diamond collections were studied by infrared spectrometry method. For reconstruction of thermal conditions of diamond formation were plotted Taylor Wayne diagrams with calculated isothermal curves. Diagrams of B2-defects distribution and H-centres were done. The conclusion about thermal formation conditions and possible belonging to the sea stream gravels were done.
