Abstract An activation analysis and neutron autoradiography have been applied to study the impurity distribution in natural diamond crystals. The impurity incorporation pattern has been studied on 〈100〉 and 〈110〉 lamellal cut from crystals of an octahedral, rhombododecahedral, and cubic habit having a zonal texture. Cobalt impurities, unlike other elements, concentrated in the centre of the middle regions of diamonds irrespective of the crystal growth shape. A heterogeneous mechanism has been suggested for natural diamond genesis.
