    OverviewGeology and occurrenceSynthetic corundumStructure and physical propertiesSee also

    Corundum is a crystalline form of aluminium oxide (Al 2O 3) typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral. It is also a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. Corundum has two primary gem varieties: ruby and sapphire. Rubies are red due to the presence of chromium, and sapphires exhibit a range of colors depending on what transition metal is present.
