Boleite was initial found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is this kind of an unusual and sophisticated mineral the definition of its chemical composition and crystal construction have undergone quite a few revisions considering the fact that its initially discovery.
The primary specimens of boleite had been discovered by Eduoard Cumenge, a French mining engineer. A further exceptional halide mineral from your exact same locale, with the same structure and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct interest 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, ΑσημÎνια Δαχτυλίδια it's got a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That is definitely, Each and every Δαχτυλιδια Φθηνα dice-like crystal of boleite is really made up of three rectangular box-like crystals Δαχτυλιδια skroutz oriented at ideal angles to each other. Boleite also has an exceedingly eye-catching Δαχτυλιδια Φθηνα indigo color and many very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, having a Mohs hardness ranking of only three to 3.5. It's got a vitreous to pearly luster. It can be 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, Δαχτυλιδια skroutz 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 actually been found 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.
