Boleite was initial discovered in Boleo, Mexico in 1891, in a region of the Baja peninsula that has grown to be renowned for unusual minerals. Boleite is this sort of an uncommon and sophisticated mineral which the definition of its chemical composition and crystal construction have undergone several revisions considering the fact that its to start with discovery.
The 1st specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the identical location, with an analogous construction and a slightly unique chemical composition, was named cumengite in honor of Cumenge.
There are various characteristics of boleite that make it of individual fascination to collectors. For one thing, it's got an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It contains major quantities of such metals, with about 49% guide, 14% copper and 9% silver. Secondly, it's got an interesting crystal structure, considering the Δαχτυλιδια Γυναικεια fact that boleite is usually pseudocubically twinned. That's, Each individual cube-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at Δαχτυλιδια ΜοντεÏνα appropriate angles to each other. Boleite also has an exceptionally desirable indigo coloration Δαχτυλιδια ΜονοπετÏα and several very exceptional transparent crystals are actually Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is kind of gentle, that has a Mohs hardness rating of only three 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 greater density. Boleite's refractive index is usually really superior at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, there are Δαχτυλίδια Γυναικεία a number of other minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit in Baja, Mexico, boleite has long been found in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in the United States; and from the Mendip Hills of Somerset, England.
