Boleite was very first found in Boleo, Mexico in 1891, inside a location with the Baja peninsula that has grown to be popular for exceptional minerals. Boleite is these an strange and complicated mineral that the definition of its chemical composition and crystal framework have gone through a number of revisions because its first discovery.
The first specimens of boleite were being uncovered by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the similar spot, with an identical composition and a rather 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 something, it has an unconventional chemical composition, currently being a hydrated direct copper silver chloride hydroxide. It contains major quantities of such metals, with about 49% lead, fourteen% copper and 9% silver. Next, ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια it has a captivating crystal construction, given that boleite is often pseudocubically twinned. That is certainly, Every cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented ΧÏυσά Δαχτυλίδια at correct angles to one another. Boleite also has an extremely interesting indigo shade and some quite rare clear crystals happen to be Slash as gemstones.

Like other halide minerals, for example fluorite, boleite Δαχτυλίδια is quite comfortable, with a Mohs hardness score of only three to 3.five. It has a vitreous to pearly Δαχτυλιδια Γυναικεια luster. It can be an unusually dense mineral, with a specific gravity of five.05. Only some minerals, including hematite and cassiterite, have the next Δαχτυλιδια skroutz density. Boleite's refractive index is additionally pretty large at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a selection of other minerals related to 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; from the Mammoth District of Arizona in America; and inside the Mendip Hills of Somerset, England.
