Alumina that occurs in a natural, crystalline state is referred to as the mineral corundum. Sometimes, corundum crystals are contaminated with trace amounts of chromium, iron, titanium, copper or magnesium. We call these crystals rubies and sapphires. After iron and steel, aluminium is the most widely used metal on Earth.

During crystallization of a granitic magma, copper is shown to prefer octahedral sites, be they in the melt or in crystalline phases. Burns and Fyfe (1964) showed that the Al 2 O 3 /(K 2 O + Na 2 O + CaO) ratio of the magma is proportional to the number of octahedral sites available in the melt. A relatively large alumina/alkali ratio will mean more octahedral sites in the melt, a higher ...

In volcanic rocks, sapphire and occasionally ruby are found in continental alkali basalt (Sutherland et al., 1998a).
