Boleite was first found out in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is becoming well-known for rare minerals. Boleite is such an unconventional and complicated mineral that the definition of its chemical composition and crystal composition have gone through numerous revisions because its first discovery.
The main specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. Another scarce 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 functions of boleite that make it of unique curiosity to collectors. For another thing, it's an unusual chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It contains major quantities of such metals, with about 49% lead, fourteen% copper and 9% silver. Secondly, it's got an interesting crystal Δαχτυλιδια swarovski structure, due to the fact boleite is always pseudocubically twinned. That may be, Δαχτυλιδια Γυναικεια Every single cube-like crystal of boleite is in fact composed of 3 Δαχτυλιδια skroutz rectangular box-like crystals oriented at right angles to one another. Boleite also has a very beautiful indigo color plus some really scarce transparent crystals are actually Lower as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly soft, by 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. Only Δαχτυλιδια ΜοντεÏνα a few minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial at two.03-2.05; 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 continues to be present in Damaged Hill in Δαχτυλίδια Γυναικεία New South Wales, Australia; within the Mammoth District of Arizona in The us; and during the Mendip Hills of Somerset, England.
