Boleite was initial found out in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is becoming well-known for rare minerals. Boleite is such an unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through many revisions considering the fact that its initially discovery.
The primary specimens of boleite had been discovered by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral from the very same area, 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 certain desire to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It incorporates important quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got an interesting crystal composition, due to the fact boleite is always pseudocubically twinned. That is, Just about every cube-like crystal of boleite is definitely composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has a really interesting indigo colour and some quite unusual transparent ΛευκόχÏυσα 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 luster. It is actually an unusually dense mineral, Δαχτυλιδια bulgari with a particular gravity of five.05. Only a few minerals, for example hematite and cassiterite, have a higher density. Δαχτυλιδια ΜοντεÏνα Boleite's refractive index can be very substantial at two.03-2.05; better than sapphire, sphene Δαχτυλιδια bulgari and demantoid garnet.
As well as cumengite, ΛευκόχÏυσα 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; while in the Mammoth District of Arizona in America; and inside the Mendip Hills of Somerset, England.
