Boleite was initial uncovered in Boleo, Mexico in 1891, in a very area on the Baja peninsula that has grown to be popular for unusual minerals. Boleite is this sort of an uncommon and sophisticated mineral which the definition of its chemical composition and crystal construction have undergone several revisions due to the fact its initially discovery.
The 1st specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the identical place, with an analogous framework and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that make it of specific curiosity to collectors. For something, it has an unconventional chemical composition, staying a hydrated direct copper silver chloride hydroxide. It contains major quantities of such metals, with about 49% guide, 14% ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια copper and nine% silver. Secondly, it's got a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That may be, Each and every dice-like crystal of boleite is really made ΧειÏοποίητα Δαχτυλίδια up of 3 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 Δαχτυλίδια Γυναικεία crystals are actually Lower as gemstones.

Like other halide Δαχτυλιδια bulgari minerals, such as fluorite, boleite is fairly soft, by using a Mohs hardness ranking 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 Δαχτυλιδια ΜοντεÏνα pretty large 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, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The us; and during the Mendip Hills of Somerset, England.
