Boleite was 1st uncovered in Boleo, Mexico in 1891, in the area on the Baja peninsula that is becoming popular for uncommon minerals. Boleite is this kind of an unusual and sophisticated mineral which the definition of its chemical composition and crystal construction have undergone quite a few revisions considering the fact that its initially discovery.
The primary specimens of boleite had been discovered by Eduoard Cumenge, a French mining engineer. A further exceptional halide mineral from your same locale, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct interest to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It incorporates important quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got an interesting crystal structure, considering that boleite is always pseudocubically twinned. That is definitely, Each and every dice-like crystal of boleite is really made up of 3 rectangular box-like crystals oriented at ideal angles to one another. Boleite also has a very beautiful indigo color and many extremely scarce transparent crystals are actually Lower as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness rating of only 3 to three.5. It's a vitreous ΑσημÎνια Δαχτυλίδια to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια few minerals, for instance hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial at two.03-2.05; better than sapphire, sphene and Δαχτυλιδια swarovski demantoid garnet.
Along with cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Δαχτυλίδια Hills of Somerset, England.
