Boleite was initially learned in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is now recognized for rare minerals. Boleite is such an unconventional and sophisticated mineral which the definition of its chemical composition and crystal structure have been through various revisions due to the fact its 1st discovery.
The initial specimens of boleite had been found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the exact site, with an identical structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of specific desire to collectors. For something, it has an strange chemical composition, getting a hydrated guide copper silver chloride hydroxide. It has considerable portions of those metals, with about forty nine% direct, fourteen% copper and 9% silver. Next, it's a captivating ΧειÏοποίητα Δαχτυλίδια crystal framework, because boleite is often pseudocubically twinned. Which is, Each individual cube-like crystal of boleite is definitely composed of a few rectangular box-like crystals oriented at proper angles to one ΧειÏοποίητα Δαχτυλίδια another. Boleite also has an incredibly appealing indigo shade and a few very Δαχτυλίδια Γυναικεία exceptional transparent crystals are Lower as gemstones.

Like other Δαχτυλιδια ΜονοπετÏα halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness rating of only 3 to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a certain gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have Δαχτυλιδια swarovski a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with 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, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
