Wiluite is a dark green, brownish, or black blocky silicate mineral with the chemical formula Ca19(Al,Mg,Fe,Ti)13(B,Al,[ ])5Si18O68(O,OH)10. It has a Mohs hardness of 6 and a specific gravity of 3.36. It has a vitreous lustre, poor cleavage and an irregular brittle fracture. It crystallizes in the tetragonal system and occurs as well-formed crystals with good external form. It is isostructural with the vesuvianite group and is associated with wollastonite and olive-green grossulars (viluites) in a serpentinized skarn.

  • Wiluit ist ein selten vorkommendes Mineral aus der Mineralklasse der „Silicate und Germanate“. Es kristallisiert im tetragonalen Kristallsystem mit der chemischen Zusammensetzung Ca19(Al,Mg,Fe,Ti)13B< 3[(O,OH)10|(SiO4)10|(Si2O7)4] und bildet meist gut entwickelte, tetragonal-dipyramidale Kristalle von dunkelgrüner, grünlichbrauner oder schwarzer Farbe.
