Boleite was initially found in Boleo, Mexico in 1891, inside a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the similar area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that make it of particular fascination to collectors. For one thing, it's got an abnormal chemical composition, being a hydrated direct copper silver chloride hydroxide. It consists of significant portions of these metals, with about 49% lead, fourteen% copper and 9% silver. Secondly, it's got an interesting crystal structure, due to the fact boleite is Δαχτυλίδια Γυναικεία always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is Δαχτυλιδια Γυναικεια in fact composed of 3 rectangular box-like crystals oriented at right angles Δαχτυλιδια skroutz to one another. Boleite also has a really beautiful indigo color plus some really scarce transparent crystals are actually Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly soft, by using a Mohs hardness rating 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 a few minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive Δαχτυλιδια Γυναικεια 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 New South Wales, Australia; within the Mammoth District of Arizona in The us; and during the Mendip Hills of Δαχτυλίδια Γυναικεία Somerset, England.
