FIELD: measuring equipment.
SUBSTANCE: invention relates to the field of diamonds investigation and examination, and can be used in gemology, during the geological prospecting performance using the “diamonds by the diamonds” searching method, for the crystals from placer deposits with diamonds from the known mother and alluvial placers comparison, as well as during the crystals batches expert evaluations, including processed stones, for their belonging to the known diamondiferous placers. Disclosed is the nitrogen-containing diamonds with a N-representative samples comparison method, based on the measurement, of nitrogen in the form of A and B or C averaged concentrations on the sample whole crystals, for example, by the IR-Fourier spectroscopy method and the n aggregation kinetics determination for the chosen order, averaged numerical values of the Knt nitrogen A-centers or C-centers aggregation integral parameter, acquired by the crystals during their genesis. At that, additionally calculating the aggregation integral parameters (lgKnt) averaged values logarithms, according to the aggregation integral parameter logarithm plotting the crystals from the samples distribution density probability smoothed function and determining the two samples statistical similarity degree by the crystal aggregation integral parameter logarithmic values discrete numerical arrays pair or the density smoothed functions comparison, for example, by the Pearson criterion, and the samples statistical similarity degree determination by the Pearson criterion is carried out, for example, using the “Pearson Analyzer of Density Functions (PADF)” software.
EFFECT: increase in the nitrogen-containing diamonds from different placers samples statistical similarity degree determination reliability.
