Like other halide minerals, for instance fluorite, boleite is very smooth, having a Mohs hardness score of only 3 to 3.five. It has a vitreous to pearly luster.

Boleite's refractive index can also be incredibly higher at two.03-two.05; greater Ασημένια Δαχτυλίδια than sapphire, sphene and demantoid garnet.

Besides cumengite, there are a number of other minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
