Zusammenfassung:The origin of most surface sculptures on diamond crystals from kimberlite results from the processes of natural etching [1]. Several experimental studies on etching of diamonds in the kimberlite melt confirming this statement [26] appeared in the last several years. However, kimberlite magma is a complex multicom ponent system evolving in a broad range of PT param eters; that is why refinement of the influence of indi vidual components on the processes of diamond etch ing is an important task.
