Boleite was first uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well known for scarce minerals. Boleite is these an strange and complicated 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 identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the identical location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are lots of attributes of boleite which make it of certain interest to collectors. For something, it has an unconventional chemical composition, getting a hydrated lead copper silver chloride hydroxide. It has considerable portions of those metals, with about forty nine% direct, 14% copper and nine% Δαχτυλίδια Γυναικεία silver. Secondly, it's a fascinating crystal framework, because boleite is often pseudocubically Δαχτυλιδια ΜονοπετÏα twinned. Which is, each cube-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at proper angles to one another. Boleite also has an incredibly appealing indigo shade and a few pretty uncommon clear crystals happen to be Slash as gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has a Mohs hardness rating of only ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια three to 3.5. It's got a vitreous to pearly luster. It's an unusually dense mineral, with a selected gravity of 5.05. Just a few minerals, such as hematite and cassiterite, have a better density. Boleite's refractive index is usually really superior at 2.03-two.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, ΧειÏοποίητα Δαχτυλίδια paralaurionite, matlockite, chlorargyrite, bideauxite, 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 ΧειÏοποίητα Δαχτυλίδια of Arizona in America; and within the Mendip Hills of Somerset, England.
