Boleite was initial learned in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is now well-known for rare 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 first discovery.
The main specimens of boleite ended up found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the identical location, with an analogous construction and a slightly unique 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, it's got an interesting crystal composition, considering that boleite is always pseudocubically twinned. That is definitely, Each and Δαχτυλιδια skroutz every dice-like crystal of boleite is really made up of 3 rectangular box-like crystals oriented at ideal angles to each other. Boleite also has a very beautiful indigo shade and some quite rare clear crystals happen to be Slice as gemstones.

Like other halide minerals, like fluorite, boleite is sort of delicate, that has a Mohs hardness rating of only three to three.5. It's a Δαχτυλιδια Φθηνα vitreous to pearly luster. It's an unusually dense mineral, with a certain gravity of five.05. Just a few minerals, Δαχτυλιδια Φθηνα which include hematite and cassiterite, have a greater density. Boleite's refractive index ΑσημÎνια Δαχτυλίδια is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As Δαχτυλίδια Γυναικεία well as cumengite, There are a selection of other minerals related to boleite, 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 America; and from the Mendip Hills of Somerset, England.
