Artificial pink corundum is produced by melting aluminum oxide together with chromium oxides in electric arc furnaces. Compared to white corundum, pink corundum alloyed with chromium has a significantly higher hardness. Corundum alloyed with chromium is characterized by a longitudinal grain shape with sharp edges and a stable specific gravity. Thanks to the perfect washing in water, the grains are clean, they have a bright pink color.
