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 undergone several revisions since its to start with discovery.
The 1st specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the exact same location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct 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 those metals, with about 49% direct, 14% copper and nine% silver. Secondly, it's a fascinating crystal composition, given that boleite is always pseudocubically twinned. That ΧειÏοποίητα Δαχτυλίδια is definitely, Each and every dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented at ideal angles to each other. ΧειÏοποίητα Δαχτυλίδια Boleite also has an exceedingly eye-catching indigo color and many very exceptional Δαχτυλίδια Γυναικεία transparent crystals are Reduce as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, using a Mohs hardness ranking of only 3 to three.five. It's a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular 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, Δαχτυλίδια Γυναικεία like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
