The chemical formula of mineral Aerinite is (Ca, Na)6FeAl(Fe+, Mg)6[Si12O36(OH)12H][(H2O)12(CO3)]. Aerinite is actually an alteration product in basalts and andesites as well as in hydrothermal zeolite deposits. It is usually found in its type of locality at Aragon, Caserras, Spain and St. Pandelon, Landes, Spain. Aerinite was named from the Greek word root aer, alluding to the atmosphere or sky and hence the color, sky blue. Aerinite is known to crystallize in the trigonal system of crystal formation.

            Aerinite is most commonly found blue, blue green or sky blue in color that could appear more interesting and more splendid when viewed with the aid of petrographic polarizing light microscopes used in the field of optical mineralogy. The specific gravity measure of the mineral is usually found 2.48. Most crystals of mineral Aerinite are found translucent in appearance. They are commonly fibrous wherein crystals are usually made up of fibers. The hardness measure of the mineral when it is evaluated with the aid of polarizing microscope used in optical mineralogy is usually found 3. Aerinite is most commonly found exhibiting vitreous luster when viewed in reflected light of polarized microscopes used in optical mineralogy. It is also most commonly found leaving bluish white streak when rubbed on a white porcelain streak plate. Aerinite is usually found showing biaxial negative figure when evaluated between crossed nicols of petrographic polarizing microscopes in optical mineralogy. The birefringence of the mineral is usually 0.0700. Aerinite is pleochroic and it usually exhibits bright blue to pale beige. Aerinite is a non-radioactive mineral.
