Boleite was initial found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming popular for uncommon minerals. Boleite is this kind of an unusual and sophisticated mineral the definition of its chemical composition and crystal construction have undergone quite a few revisions considering the fact that its initially discovery.
The 1st specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the identical place, with an analogous framework and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that make it of particular desire to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal framework, because boleite is often pseudocubically twinned. Which is, each dice-like crystal of Δαχτυλίδια Γυναικεία boleite is actually made up of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally desirable indigo coloration and several extremely exceptional transparent ΧειÏοποίητα Δαχτυλίδια crystals are actually Lower as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly Δαχτυλίδια 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, Δαχτυλιδια Γυναικεια with a certain gravity of five.05. Only 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 than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related to boleite, which Δαχτυλιδια Φθηνα include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; while in the Mammoth District of Arizona in America; and within the Mendip Hills of Somerset, England.
