Boleite was initial discovered in Boleo, Mexico in 1891, inside of a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unusual and sophisticated mineral the definition of its chemical composition and crystal composition have been through many revisions considering that its very first discovery.
The initial specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral through 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 fascination to collectors. For one thing, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It is made up of substantial portions of such metals, with about forty nine% direct, 14% copper and ΧειÏοποίητα Δαχτυλίδια nine% silver. Secondly, it's an interesting crystal structure, considering the fact that boleite is usually pseudocubically twinned. That's, Each individual cube-like crystal of boleite is ΧÏυσά Δαχτυλίδια actually composed of a few rectangular box-like crystals oriented at appropriate angles Δαχτυλίδια to each other. Boleite also has an incredibly appealing indigo coloration and several very exceptional clear crystals have been Δαχτυλιδια bulgari Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of comfortable, with a Mohs hardness score of only three to 3.five. It has a vitreous to pearly luster. It truly is an unusually dense mineral, with a specific gravity of 5.05. Only some minerals, including hematite and cassiterite, have the next density. Boleite's refractive index can also be incredibly higher at two.03-2.05; Δαχτυλίδια Γυναικεία increased than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; from the Mammoth District of Arizona in The usa; and while in the Mendip Hills of Somerset, England.
