AlAl6BSi3O18

Dumortierite is a borosilicate mineral with the chemical formula aluminum aluminum six boron silicon three oxide eighteen. It crystallizes in the orthorhombic system and is classified under the Strunz classification as 9.AJ.10. The mineral typically exhibits a white streak and displays a vitreous to dull luster. It is usually found in shades of blue, gray, or brown. Dumortierite has a hardness of approximately 7 to 7.5 on the Mohs scale and a relatively high density.
