Boleite was first uncovered in Boleo, Mexico in 1891, in the area from the Baja peninsula that has become famous for exceptional minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have undergone several revisions considering the fact that its initially discovery.
The primary specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the identical location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of certain interest to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It has important quantities of those metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's a fascinating crystal composition, given that boleite is often pseudocubically twinned. That is definitely, Every single cube-like crystal of boleite is definitely composed of a few rectangular box-like crystals oriented at proper angles to one another. Boleite also has an incredibly appealing indigo shade and a few pretty unusual clear crystals are already Reduce as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, using a Mohs hardness ranking of only 3 to three.5. Ασημένια Δαχτυλίδια It's a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for example hematite and cassiterite, have an increased density. Boleite's refractive index is additionally very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with Δαχτυλιδια Γυναικεια cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the Δαχτυλιδια swarovski deposit in Baja, Mexico, boleite has become located in Broken Hill in Δαχτυλιδια Γυναικεια New South Wales, Australia; inside the Δαχτυλιδια skroutz Mammoth District of Arizona in America; and in the Mendip Hills of Somerset, England.
