Boleite was 1st uncovered in Boleo, Mexico in 1891, within a region from the Baja peninsula that has grown to be popular for unusual minerals. Boleite is this sort of an uncommon and complex mineral which the definition of its chemical composition and crystal construction have undergone several revisions since its to start with discovery.
The 1st specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral with the identical place, with an analogous framework and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that make it of specific fascination to collectors. For something, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal construction, because boleite is often pseudocubically twinned. That is certainly, Every dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια at ideal angles to each other. Boleite also has a very beautiful indigo color and many very uncommon clear crystals have already been cut as gemstones.

Like other halide minerals, for instance fluorite, boleite ΧειÏοποίητα Δαχτυλίδια is very tender, using a Mohs hardness ranking of only 3 to three.5. It's a vitreous to pearly luster. Δαχτυλίδια It is an unusually dense mineral, with a certain gravity of five.05. Only a few minerals, for instance hematite Δαχτυλιδια Γυναικεια and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-two.05; bigger than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, Δαχτυλιδια Φθηνα mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has actually been found in 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.
