Boleite was very first discovered in Boleo, Mexico in 1891, in a location on 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 rare halide mineral within the similar area, with a similar composition and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite that make it of particular fascination to collectors. For one thing, it's got an abnormal 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 9% silver. Next, it has a captivating crystal composition, considering that boleite is always pseudocubically twinned. That is definitely, Each and every dice-like crystal of boleite is in fact made up of 3 rectangular box-like crystals oriented at right angles to each other. Boleite also has a very beautiful indigo colour and many Δαχτυλίδια Γυναικεία extremely scarce transparent crystals are actually Lower as gemstones.

Like other halide minerals, such as fluorite, Δαχτυλίδια Γυναικεία boleite is fairly soft, by using a Mohs hardness rating of only Δαχτυλιδια Γυναικεια 3 to three.5. It's a vitreous to pearly luster. It is an Δαχτυλιδια skroutz 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 a variety 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; inside the Mammoth District of Arizona in Δαχτυλιδια swarovski The usa; and in the Mendip Hills of Somerset, England.
