Boleite was initial found in Boleo, Mexico in 1891, inside a region of your Baja peninsula that happens to be renowned for unusual minerals. Boleite is this sort of an uncommon and sophisticated mineral which the definition of its chemical composition and crystal framework have undergone several revisions since its to start with discovery.
The main specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the identical place, with an analogous framework and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are various characteristics of boleite that make it of individual fascination to collectors. For one thing, it's got an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of such metals, with about 49% Δαχτυλιδια swarovski lead, fourteen% copper and 9% silver. Secondly, Δαχτυλιδια Φθηνα it's got an interesting crystal structure, due to the fact boleite is always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a really beautiful indigo colour plus some really scarce transparent crystals have been Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is kind of gentle, by using a Mohs hardness rating of only 3 to 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 Δαχτυλίδια to boleite, which include 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 ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια Wales, Australia; inside the Mammoth District of ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια Arizona in The usa; and in the Mendip Hills of Somerset, England.
