Boleite was 1st uncovered in Boleo, Mexico in 1891, in the area from the Baja peninsula that has become famous for exceptional minerals. Boleite is these an strange and complicated mineral that the definition of its chemical composition and crystal composition have gone through numerous revisions because its first discovery.
The first specimens of boleite were being uncovered by Eduoard Cumenge, a French mining engineer. Yet another rare halide mineral within the similar spot, with a similar composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are many options of boleite which make it of specific fascination 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 construction, since boleite is often pseudocubically twinned. That's, each dice-like crystal of boleite is actually made up of three rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally desirable Δαχτυλίδια Γυναικεία indigo coloration and several very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness ranking of only 3 to three.5. It's a vitreous to pearly ΧειÏοποίητα Δαχτυλίδια luster. It is an unusually dense mineral, with a certain gravity of five.05. Only a few minerals, for Δαχτυλίδια Γυναικεία instance hematite and cassiterite, have a greater density. Boleite's refractive index is Δαχτυλιδια Γυναικεια usually really superior at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As Δαχτυλιδια skroutz well as 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 become located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in America; and within the Mendip Hills of Somerset, England.
