Like other halide minerals, for instance fluorite, boleite is very smooth, having a Mohs hardness ranking of only 3 to 3.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a specific gravity of 5.05. Only some minerals, including hematite and cassiterite, have the next density. Boleite's refractive index can also be incredibly higher at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
In addition Δαχτυλίδια Γυναικεία to cumengite, There are a variety of other minerals affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite continues to be present in Δαχτυλιδια ΜονοπετÏα Damaged Hill in New South Wales, Australia; within the Mammoth District of Δαχτυλιδια skroutz Arizona in The usa; and during ΧÏυσά Δαχτυλίδια the Mendip Hills of Somerset, England.
