Boleite was very first identified in Boleo, Mexico in 1891, within a region from the Baja peninsula that has become famous for exceptional minerals. Boleite is these an abnormal and complex mineral that the definition of its chemical composition and crystal framework have gone through a number of revisions because its first discovery.
The main specimens of boleite ended up found by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral with the identical place, with a similar framework and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite which make it of certain 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, fourteen% copper and nine% silver. Secondly, it's got an interesting crystal structure, due to the fact boleite is often pseudocubically twinned. That is certainly, Each and every dice-like crystal of boleite is in fact made Δαχτυλίδια up of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a very beautiful indigo colour plus some quite rare clear crystals have been Slice as ΧειÏοποίητα Δαχτυλίδια gemstones.

Like other halide minerals, like fluorite, boleite is kind of delicate, that has a Mohs Δαχτυλίδια hardness rating of only three to 3.5. It's got a vitreous to Δαχτυλιδια Γυναικεια pearly luster. It's an unusually dense mineral, with a certain gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have a better density. Boleite's refractive index is usually very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, Δαχτυλιδια Φθηνα atacamite, mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; while in the Mammoth District of Arizona in America; and inside the Mendip Hills of Somerset, England.
