Boleite was initially found in Boleo, Mexico in 1891, in a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and complicated 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 uncovered by Eduoard Cumenge, a French mining engineer. Yet another rare 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 Δαχτυλιδια swarovski to the fact boleite is always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is in fact made up of 3 rectangular Δαχτυλιδια ΜοντεÏνα box-like crystals oriented at right angles to one another. Boleite also has Δαχτυλιδια ΜονοπετÏα a very beautiful indigo colour plus some really scarce transparent crystals are actually ΧÏυσά Δαχτυλίδια 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 an unusually dense mineral, with a certain gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are Δαχτυλιδια Γυναικεια a selection of other minerals associated 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 Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
