Spinel (natural magnesium aluminate) is a mineral from the category of magnesium oxides that crystallizes in the cubic system, having the chemical formula MgAl2O4.
In its natural form as well-developed crystals, spinel is frequently found in igneous rocks but also in metamorphic rocks such as marble in the form of octahedral crystals, rarely as twin crystals.
It can also be found in gravel (sedimentary rocks). The best known geographical regions where the mineral was found are Sri Lanka, Myanmar or Pakistan.
