Boleite was first learned in Boleo, Mexico in 1891, in a very area in the Baja peninsula that is now well known for scarce minerals. Boleite is these types of an strange and complicated mineral that the definition of its chemical composition and crystal composition have gone through a number of revisions because its first discovery.
The main 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 plenty of characteristics of boleite that make it of individual curiosity to collectors. For one thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got an interesting crystal composition, considering that boleite is always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at correct angles to one ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια another. Boleite also has an extremely interesting indigo shade and some quite rare clear crystals happen to be Slice as gemstones.

Like other halide minerals, like fluorite, boleite is sort of delicate, that has a Mohs hardness rating of only three to three.5. It's got a vitreous to pearly luster. It is an unusually dense mineral, with a certain gravity of five.05. Just a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger ΧÏυσά than sapphire, sphene and demantoid garnet.
In combination with cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition ΧÏυσά to the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; inside ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια the Mammoth District of Arizona in America; and within the Mendip Hills Δαχτυλιδια ΜοντεÏνα of Somerset, England.
