Boleite was initial found out in Boleo, Mexico in 1891, within a region from the Baja peninsula that happens to be 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 first discovery.
The main specimens of boleite ended up 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 plenty of capabilities of boleite that make it of specific desire to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper Δαχτυλίδια Γυναικεία and 9% silver. Next, it has a captivating crystal construction, since boleite is often pseudocubically twinned. That's, Each individual cube-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an incredibly appealing indigo coloration and some pretty unusual clear crystals are Δαχτυλιδια ΜοντεÏνα already Reduce as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, using a Mohs hardness ranking of only 3 to three.five. It has a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial ΧÏυσά Δαχτυλίδια 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, ΧÏυσά 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 ΧÏυσά Δαχτυλίδια Arizona in The us; and from the Mendip Hills of Somerset, England.
