Boleite was 1st found in Boleo, Mexico in 1891, inside a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is this sort of an uncommon and sophisticated mineral which the definition of its chemical composition and crystal construction have undergone quite a few revisions considering the fact that its to start with discovery.
The 1st specimens of boleite ended up identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the identical location, with an analogous construction and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are plenty of capabilities of boleite that make it of particular fascination to collectors. For one thing, it's got an abnormal chemical composition, becoming a hydrated direct copper silver chloride hydroxide. It has considerable quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got an interesting crystal structure, considering the fact that boleite is usually pseudocubically twinned. That's, Each individual cube-like crystal of boleite is definitely composed of Δαχτυλιδια ΜονοπετÏα a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has a really interesting indigo shade and some incredibly uncommon clear ΛευκόχÏυσα crystals have already been Reduce as gemstones.

Like other 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'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 quite high at two.03-two.05; larger than sapphire, sphene and demantoid garnet.
In addition to ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια cumengite, Δαχτυλιδια Γυναικεια There are a variety of other minerals associated with boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has actually been found in Broken Hill in New South Wales, Australia; in the Mammoth District of Arizona in The us; and from the Mendip Hills of Somerset, Δαχτυλιδια ΜοντεÏνα England.
