Boleite was initial identified in Boleo, Mexico in 1891, inside a region of the Baja peninsula that happens to be famous for exceptional minerals. Boleite is these an abnormal and complex mineral which the definition of its chemical composition and crystal framework have gone through a number of revisions considering the fact that its initial discovery.
The very first specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral from your same locale, with a similar construction and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite that make it of specific fascination to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It is made up of major portions of these metals, with about forty nine% direct, fourteen% copper and 9% silver. Next, it's a fascinating crystal framework, given that boleite is always pseudocubically twinned. That is definitely, Each and every cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a really beautiful indigo colour plus some quite rare clear crystals ΛευκόχÏυσα have been Minimize as gemstones.

Like other halide minerals, like fluorite, boleite is kind of gentle, that has a Mohs hardness rating of only three to three.5. It's a vitreous to pearly luster. It's an ΛευκόχÏυσα unusually dense mineral, with a certain gravity of five.05. Just a few minerals, which include hematite and cassiterite, have ΧÏυσά Δαχτυλίδια a greater density. Boleite's refractive index is usually really significant at 2.03-two.05; bigger than sapphire, sphene and demantoid Δαχτυλίδια Γυναικεία garnet.
As well as cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, 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 of Arizona in America; and within the ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια Mendip Hills of Somerset, England.
