Boleite was 1st uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well known for scarce minerals. Boleite is these types of an abnormal and complex mineral which the definition of its chemical composition and crystal framework 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. Another scarce halide mineral with the identical location, with an analogous construction and a slightly unique chemical composition, was named cumengite in honor of Cumenge.
There are various characteristics of boleite that make it of individual curiosity to collectors. For one thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal framework, because boleite is often pseudocubically twinned. Which is, each dice-like crystal of boleite is actually made up of three rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally appealing indigo coloration and a few pretty unusual Δαχτυλίδια clear crystals are already cut as gemstones.

Like other halide minerals, for instance fluorite, boleite is very smooth, using a Mohs hardness ranking of only 3 to three.5. It's a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια Only a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other Δαχτυλίδια Γυναικεία minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, Δαχτυλιδια ΜονοπετÏα bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has Δαχτυλιδια bulgari long been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and inside the Mendip Hills of Somerset, England.
