Boleite was 1st uncovered in Boleo, Mexico in 1891, in the 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 numerous revisions because its initial discovery.
The first specimens of boleite were being uncovered by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral in the same site, with an identical framework and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of certain interest to collectors. For another thing, it has an unusual chemical composition, staying a hydrated direct copper silver chloride hydroxide. It contains major quantities of such metals, with about 49% guide, fourteen% copper and Δαχτυλίδια 9% silver. Secondly, it's got an interesting crystal structure, due to the fact boleite is usually pseudocubically twinned. That is, Just about every cube-like crystal Δαχτυλιδια Γυναικεια of boleite is definitely composed of a few rectangular box-like crystals oriented at proper angles to one another. Δαχτυλιδια bulgari Boleite also has an extremely attractive indigo shade and a few incredibly uncommon clear crystals have already been Slash as gemstones.

Like other halide minerals, for example fluorite, boleite is quite comfortable, with a Mohs hardness score of only three to 3.five. It's got a vitreous to pearly luster. It really is an unusually dense mineral, with a selected gravity of 5.05. Only some minerals, like hematite and cassiterite, have an increased density. Boleite's refractive index is also ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια incredibly superior at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has ΧÏυσά Δαχτυλίδια actually been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and inside the Mendip Hills of Somerset, England.
