Реферат:	eng: New data on the study of residual pressure in mineral inclusions in diamonds from kimberlite pipes and placers of Yakutia obtained using Raman Spectroscopy are presented. Calculated values of residual pressure in olivine and coesite inclusions in kimberlite diamonds according to works of Israeli et al [1] and Sobolev et al [2] indicate that the host crystal crystallized at the depth not less than 165 km, at pressure of 4.8-5.0 GPa and temperature T=1200 °C. Comparative analysis of Raman spectra of olivine inclusions in diamonds from placers of Ebelyakh river on inclusions, contained in diamond and then brought to the surface, showed that olivine inclusions are less stressed. The structural orientation of olivine inclusions in diamonds from placers of Ebelyakh river possibly plays a role in these differences of Raman spectra. © Published under licence by IOP Publishing Ltd.
