Celestite Cluster | Madagascar selenite 5 and 4 on theThis celestite cluster comes from Madagascar and features translucent blue to blue gray crystals naturally formed on a light colored matrix. Celestite, also known as celestine, is a strontium sulfate mineral with the chemical formula SrSO and crystallizes in the orthorhombic system. The crystals often form in sharp, well defined shapes with a glassy luster, making celestite a favorite among mineral collectors. With a Mohs hardness of 33. 5, celestite
