Corundum is the mineral/crystalline form of Aluminium Oxide, and is mainly mined from metamorphic rocks such as schists, gneiss and marbles. Corundum can also be mined from pegmatites, seyenite and ultramafic intrusive rocks. The varying colouration of corundum is due to chemical impurities, ie, chromium present in the crystal will give it a red colour - hence the gemstone will be a ruby.
