Реферат:	eng: The carbon isotope fractionation factor between diamond and carbon dissolved in the Fe-Ni metal melt varies from 4.1‰ down to 2.4‰ in HTHP crystallization experiments with the average diamond growth rates ranging from 1 to 12.5 mg/h. The observed fractionation of heavy carbon isotope is in agreement with the Burton-Prim-Slichter model for the compatible impurity distribution associated with crystallization. The variations in the carbon isotope composition within a single diamond crystal can result from appropriate variations of the crystal growth rate. The scale of the observed fractionation effect is comparable with the internal isotope inhomogeneity of natural stones. © 2011 Elsevier B.V. All rights reserved.
