Boleite Strange Gemstones




Boleite was initial found out in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is becoming well-known for rare minerals.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has a Mohs hardness score of Χρυσά Δαχτυλίδια only three to 3.five. It's got a vitreous to pearly luster. It really is an unusually dense mineral, with a selected gravity of 5.05. Just a few minerals, such as hematite and cassiterite, have a better density. Boleite's refractive index is usually really superior at 2.03-two.05; bigger than sapphire, sphene and demantoid garnet.

As well as cumengite, There are a selection of other Δαχτυλιδια Φθηνα minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
