1. A method of reducing the temperature-time conditions genesis type IaAB diamonds or mixed type Ib-IaA, based on the calculation of the local concentration of the impurity C in nitrogen forms, A and B in the crystal is measured, e.g., by IR microspectroscopy, local values of the integral parameter aggregation kinetics Kt n-th order corresponding nitrogen centers, determining the temperature and time of the genesis, characterized in that it additionally register the change of the integral parameter values corresponding to the aggregation of nitrogen centers Δ (Kt) by crystal growth layers, for example, in any field of fine diamond plate intersecting the growth layers, and the determination of the temperature T and the time Δt genesis carried out uravneniyaAexp (-E / kT) × Δt = Δ (Kt), where: k- Boltzmann constant, Au E- constant and the Arrhenius activation energy aggregation C- or A-centers corresponding order kinetics n.2 aggregation. A method according to claim 1, characterized in that the admissible pairs of values of temperature T and Δt the duration of continuous growth of the crystal region is determined by the magnitude and uniform monotonic decrease aggregation of the integral parameter Δ (Kt) by layers selected region.3 growth. A method according to claim 1, characterized in that the admissible pairs of temperature T and the duration Δt postrostovogo host crystal diamond values in the isothermal pattern is determined by the value of the integral parameter corresponding aggregation nitrogen centers (Kt) near the undissolved portion of the outer surface of the crystal, where A (Kt) is received equal to (Kt) .4. A method according to claim 1, characterized in that the pairs of values allowable duration Δt and temperature
