Boleite was first learned in Boleo, Mexico in 1891, in a very area in the Baja peninsula that is now well-known for rare minerals. Boleite is these types of an strange and complicated mineral that the definition of its chemical composition and crystal composition have gone through numerous revisions because its to start with discovery.
The 1st specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the identical place, with an analogous framework and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are various functions of boleite that make it of unique curiosity to collectors. For another thing, it's an unusual chemical composition, staying a hydrated direct copper silver chloride hydroxide. It contains important quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got a fascinating crystal framework, given that boleite is often pseudocubically twinned. That is certainly, Every dice-like crystal of boleite is actually made up Δαχτυλίδια of three rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally appealing indigo shade and a few incredibly uncommon clear crystals happen to be Slash Δαχτυλίδια Γυναικεία as gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has Δαχτυλιδια Γυναικεια a Mohs hardness rating of only three to 3.5. It's got a vitreous ΛευκόχÏυσα 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 greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related to boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Δαχτυλίδια Γυναικεία Mexico, boleite is 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.
