Boleite was initially 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 unconventional 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 learned by Eduoard Cumenge, a French mining engineer. One more uncommon 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 desire to collectors. For something, it has an strange chemical composition, getting a hydrated lead copper silver chloride hydroxide. It has important quantities of such metals, with about forty nine% guide, 14% copper and nine% silver. Secondly, it's got a fascinating crystal composition, due to the fact boleite is always pseudocubically twinned. That is, Every single cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at correct Δαχτυλιδια ΜονοπετÏα angles to one another. Boleite also has a really interesting indigo colour plus some quite rare clear crystals have been Slice as gemstones.

Like other halide minerals, like fluorite, boleite is sort of delicate, Δαχτυλιδια bulgari that has a Mohs hardness rating of only three to three.5. It Δαχτυλιδια skroutz has a vitreous to pearly luster. It can be an unusually dense mineral, with a specific gravity of five.05. Only some minerals, for example hematite and cassiterite, have the next 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 variety of other minerals associated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the Δαχτυλίδια Γυναικεία deposit in Baja, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
