Abstract
Natural and polished (111) octahedral faces and polished (100) cube faces of diamonds have been etched in strong oxidizing agents like potassium chlorate (KClO3) and sodium perchlorate (NaClO4) at various temperatures. Pits of both orientations are produced and the mechanism of formation of such pits has been described. It is shown for the first time that etch can be initiated at such a low temperature as about 380°C and even at this temperature the pits can be formed of negative orientation on octahedral faces.Keywords
