How to Soften a Diamond (IMAGE)
Caption
Material removal mechanism during diamond polishing: a sharp-edged diamond particle (gray atoms in the upper left) »peels off« a dust particle from the glass-like phase (green atoms) at the surface of the diamond (gray atoms in the lower part of the figure). At the same time, oxygen from the air (red atoms) reacts with the carbon chains (brown atoms) at the surface to form carbon dioxide.
