Boleite was to start with uncovered in Boleo, Mexico in 1891, in the region from the Baja peninsula that has become well known for scarce minerals. Boleite is these types of an unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its very first discovery.
The very first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more 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 options of boleite which make it of certain desire to collectors. For something, it has an strange 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 a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That is definitely, Each and every dice-like crystal of boleite is really made Δαχτυλιδια ΜονοπετÏα up of 3 rectangular box-like crystals oriented at ideal angles to each other. Boleite also has a very beautiful indigo colour plus some really scarce Δαχτυλιδια ΜονοπετÏα transparent crystals are actually Minimize as gemstones.

Like other halide Δαχτυλιδια skroutz minerals, such as fluorite, boleite is kind of soft, by using a Mohs hardness rating of only 3 to ΧÏυσά Δαχτυλίδια three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a certain gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related to boleite, which ΑσημÎνια Δαχτυλίδια 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.
