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 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 learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the similar spot, with a similar composition and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of specific fascination to collectors. For something, it's got an abnormal chemical composition, being a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about 49% lead, fourteen% copper and 9% silver. Secondly, it's got an interesting crystal structure, Δαχτυλιδια Γυναικεια 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 Δαχτυλίδια Γυναικεία 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 index can be very large at two.03-2.05; increased than sapphire, sphene and ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια 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 ΧειÏοποίητα Δαχτυλίδια be present in Damaged Hill in New South Wales, Australia; within the Mammoth Δαχτυλίδια District of Arizona in The usa; and during the Mendip Hills of Somerset, England.
