Boleite was initial learned in Boleo, Mexico in 1891, in a very area in the Baja peninsula that is now well known for scarce minerals. Boleite is these types of an strange and complicated mineral that the definition of its chemical composition and crystal composition have been through various revisions due to the fact its 1st discovery.
The primary specimens of boleite had been discovered by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral from your same locale, with the same structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are numerous features of boleite which make it of certain interest to collectors. For another thing, it has an unconventional chemical composition, staying a hydrated lead copper silver chloride hydroxide. It contains important quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got an interesting crystal composition, considering that boleite is always pseudocubically twinned. That may be, Each and every dice-like crystal of boleite is in fact made up of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a very beautiful indigo colour plus some really Χειροποίητα Δαχτυλίδια scarce transparent crystals are actually Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly soft, by using a Χειροποίητα Δαχτυλίδια Mohs hardness ranking of only three to Δαχτυλίδια Γυναικεία 3.five. It has a vitreous to pearly luster. It is actually an Δαχτυλιδια bulgari unusually dense mineral, with a particular 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; bigger than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has actually been found in Broken Hill in New South Wales, Australia; Δαχτυλιδια Γυναικεια from the Mammoth District of Arizona in the United States; and inside the Mendip Hills of Somerset, England.
