Boleite was to start with discovered in Boleo, Mexico in 1891, in a location with the Baja peninsula that is becoming well-known for uncommon minerals. Boleite is this kind of an unusual and sophisticated 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 distinctive chemical composition, was named cumengite in honor of Cumenge.
There are plenty of capabilities of boleite that make it of particular fascination to collectors. For one thing, it's an uncommon chemical composition, being a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper and Δαχτυλίδια Γυναικεία 9% silver. Next, it has a captivating crystal construction, since boleite is usually pseudocubically twinned. Which is, Each individual cube-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at appropriate angles to one another. Boleite also has an incredibly appealing indigo coloration and a few pretty unusual clear crystals are already Slash as gemstones.

Like other halide minerals, like fluorite, boleite is kind of delicate, which has a Mohs hardness rating of only Δαχτυλιδια ΜονοπετÏα three to 3.five. It's got a vitreous to pearly luster. It really is an unusually dense mineral, with a selected gravity of 5.05. Just a Δαχτυλιδια bulgari few minerals, such as hematite and cassiterite, have an increased density. Boleite's refractive Δαχτυλιδια skroutz index can also be incredibly higher at two.03-2.05; larger than sapphire, sphene ΧειÏοποίητα Δαχτυλίδια and demantoid garnet.
In addition to cumengite, There are a variety of other minerals affiliated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, 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 Arizona in America; and within the Mendip Hills of Somerset, England.
