Boleite was 1st uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well-known for rare minerals. Boleite is these an unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its very first discovery.
The very first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more exceptional 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 plenty of characteristics of boleite that make it of individual fascination to collectors. For one thing, it's got an uncommon chemical composition, remaining a hydrated guide copper silver chloride hydroxide. It is made up of substantial portions of those metals, with about forty nine% direct, fourteen% copper and 9% silver.

Like other halide minerals, for example fluorite, boleite is quite comfortable, with a Δαχτυλιδια swarovski Mohs hardness rating of only three Δαχτυλιδια ΜονοπετÏα to 3.5. It's got a vitreous to 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 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, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In Δαχτυλίδια Γυναικεία addition to the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
