The chemical formula of mineral Aliettite is indicated by Mg3Si4O10(OH)2Ca0.1Na0.2AlFe2+0.7 Mg0.5Al3SiO10(OH)2-3(H2O). Aliettite most commonly found at low temperature environments in ancient lake sediments. They are also found in low-grade Magnesium-rich metamorphic rocks. Aliettite is most commonly found at its type of locality including Italy and California, USA. Aliettite was named after the clay mineralogists, Andrea Alietti. Aliettite is known to crystallize in the monoclinic system of crystal formation. In optical mineralogy, the monoclinic system of crystal formation comprises crystals having three axes of unequal lengths. Two of which are usually found in a position that is oblique or not perpendicular to one another. However, both of which are commonly found perpendicular to the third axis.

 Mineral Aliettite is known to exhibit perfect cleavage that can be found more clearly visible when evaluated with the aid of petrographic polarizing light microscope used in the field of optical mineralogy. Aliettite is most commonly found white, dark green or buff in hand sample. But they usually appear translucent in thin section. The crystal habit of the mineral Aliettite usually include microscopic crystals or crystals that visible only with polarizing microscopes used in optical mineralogy. They can be also found platy or sheet forms. The hardness measure of the mineral Aliettite when evaluated using the Mohs scale method is usually forms 1 to 2. Mineral Aliettite is usually found showing earthy or dull luster when the mineral is evaluated in reflected light of polarizing microscopes used in optical mineralogy. Mineral Aliettite is most commonly found leaving a white streak when rubbed on a white porcelain streak plate. Aliettite is most commonly found showing uniaxial figure when viewed between crossed nicols of petrographic polarizing microscope. Aliettite is known to have 0.0110 birefringence. Aliettite is a non-radioactive mineral as evaluated.
