Boleite was to start with learned in Boleo, Mexico in 1891, in a very area from the Baja peninsula that happens to be famous for exceptional minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have undergone several revisions considering the fact that its initially discovery.
The primary specimens of boleite had been discovered by Eduoard Cumenge, a French mining engineer. A further exceptional halide mineral from your exact same locale, with the same structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are many options of boleite which make it of specific desire to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It incorporates important quantities of such metals, with about 49% guide, 14% copper and nine% silver.

ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια That is definitely, Each and every dice-like ΧειÏοποίητα Δαχτυλίδια crystal of boleite is really made up of three rectangular box-like crystals oriented at ideal angles to each other. Boleite also has a very eye-catching indigo color and many extremely scarce transparent crystals are actually Lower as gemstones.

Like other halide minerals, such as fluorite, boleite is quite smooth, having a Mohs hardness score of only three to 3.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a specific gravity of five.05. Only some minerals, including hematite and cassiterite, have the next density. Boleite's refractive index is additionally pretty large at two.03-2.05; larger than sapphire, sphene and demantoid garnet.
In combination with cumengite, There Δαχτυλιδια ΜονοπετÏα are a variety of other minerals affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Besides the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in New South Wales, Australia; within the Mammoth District of Δαχτυλιδια bulgari Arizona in The usa; and during the Mendip Hills of Somerset, England.
