Rankinite
Rankinite is a calcium silicate mineral with the chemical formula Ca3Si2O7. It crystallizes in the monoclinic system and belongs to the tectosilicate class, as indicated by its Strunz classification (9.BC.15) and Dana classification (55.3.1.1). This mineral is typically white or colorless and exhibits a vitreous luster. It has a relatively low hardness on the Mohs scale and a moderate density. Rankinite is a rare mineral, and its properties are largely consistent with those of other tectosilicates. It is not commonly found in nature and is of interest primarily to mineral collectors and researchers.
