Boleite was initially found out in Boleo, Mexico in 1891, inside of 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 construction have undergone quite a few revisions considering that its 1st discovery.
The primary specimens of boleite had been discovered by Eduoard Cumenge, a French mining engineer. A further exceptional halide mineral through the exact same location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct interest to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It contains important quantities of such metals, with about 49% guide, ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια 14% copper and nine% silver. Secondly, it's a fascinating crystal composition, considering that 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 ΧÏυσά Δαχτυλίδια at ideal angles to one another. Boleite also has an exceptionally appealing ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια indigo coloration and several very exceptional transparent crystals are Lower as gemstones.

Like other halide minerals, Δαχτυλίδια Γυναικεία 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 an unusually dense mineral, with a certain gravity of five.05. Only a few minerals, for instance Δαχτυλιδια ΜονοπετÏα 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 is located in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and while in the Mendip Hills of Somerset, England.
