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 the definition of its chemical composition and crystal structure have been through many revisions given 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 very same area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are plenty of capabilities of boleite that make it of particular fascination to collectors. For one thing, it's got an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of such metals, with about forty nine% lead, fourteen% copper and 9% silver. Secondly, it's got an ΧÏυσά Δαχτυλίδια interesting crystal structure, due to the fact boleite is always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a really beautiful indigo colour 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, Δαχτυλιδια bulgari with a particular gravity of five.05. Only a few minerals, for instance 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, Δαχτυλιδια ΜοντεÏνα mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in Δαχτυλιδια Γυναικεια New South Wales, Australia; within the Mammoth District of Arizona in The usa; and during the Mendip Hills of Δαχτυλιδια Φθηνα Somerset, England.
