Boleite was initially uncovered in Boleo, Mexico in 1891, within a region of the Baja peninsula that happens to be famous for exceptional minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have undergone quite a few revisions considering the fact that its 1st 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 lots of attributes of boleite which make it of distinct interest to collectors. For another thing, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It incorporates major quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's a fascinating crystal framework, because boleite is often pseudocubically twinned. Which is, each dice-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια appropriate angles to each other. Boleite also has an incredibly appealing indigo coloration and a few pretty unusual clear crystals have already been cut as gemstones.

Like other halide minerals, for example fluorite, boleite ΧειÏοποίητα Δαχτυλίδια is quite comfortable, with a Mohs hardness score of only three to 3.five. Δαχτυλίδια It's a vitreous to pearly luster. It can be an unusually dense mineral, with a specific gravity of five.05. Only some minerals, including hematite and Δαχτυλιδια Γυναικεια cassiterite, have the next density. Boleite's refractive index is additionally pretty large at two.03-2.05; better than sapphire, sphene and 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 combination with the deposit in Baja, Mexico, boleite is present in Δαχτυλιδια swarovski Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and while in the Mendip Hills of Somerset, England.
