    Deep blue sapphires are blue due to the presence of titanium and iron. Synthetic corundum was first created in 1837 and in 1903 the manufacture of corundum became more large scale. Originally synthesized to make rubies, now corundum is synthesized to make lenses for satellites, scratch resistant , and other high strength optical materials.

    Corundum is a crystalline form of aluminium oxide (Al 2 O 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.

  • Ruby and Sapphire: Gems of the Mineral Corundum

    Mining small gems from hard rock is possible, but it is very expensive, and many of the gems are broken during the mining process. Fortunately, corundum is very hard and resistant to weathering. In many areas, natural weathering and erosion have liberated the stones from their host rock, and carried them into streams over long periods of

  • Corundum mineral Britannica

    Corundum in its pure state is colourless, but the presence of small amounts of impurities can impart a broad range of hues to the mineral. Ruby owes its red colour to chromium, sapphire its blue shades to the presence of iron and titanium; most corundum contains nearly 1 percent iron oxide. The mineral readily weathers to other aluminous minerals—e.g., margarite, zoisite, sillimanite, and
