Boleite was to start with uncovered in Boleo, Mexico in 1891, in the area from the Baja peninsula that has become famous for scarce minerals. Boleite is these an abnormal and complex mineral which the definition of its chemical composition and crystal framework have gone through a number of revisions because its to start with discovery.
The main 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 functions 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 such metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has an interesting crystal structure, considering the fact that boleite is usually pseudocubically twinned. That is, Just about every cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια an extremely attractive indigo shade and some quite uncommon clear crystals happen to be Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has a Mohs hardness rating of only three to 3.5. It's got a vitreous to pearly luster. It's an unusually dense mineral, with a certain gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have a greater density. Boleite's refractive index is usually really superior at 2.03-two.05; ΧÏυσά Δαχτυλίδια bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, ΧειÏοποίητα Δαχτυλίδια matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has become located in Broken Δαχτυλίδια Γυναικεία Hill in New South Wales, Australia; while in the Mammoth District of Δαχτυλιδια bulgari Arizona in America; and within the Mendip Hills of Somerset, England.
