Boleite was very first found in Boleo, Mexico in 1891, within a region of the Baja peninsula that happens to be famous for exceptional minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have gone through a number of revisions since its to start with discovery.
The main specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral with the very same location, with the same construction and a rather unique chemical composition, was named cumengite in honor of Cumenge.
There are various capabilities of boleite that make it of particular fascination to collectors. For one thing, it's got an strange chemical composition, remaining a hydrated guide copper silver chloride hydroxide. It has substantial portions of these metals, with ΛευκόχÏυσα about forty nine% lead, fourteen% copper and 9% silver. Next, it's a captivating crystal framework, given that boleite is often pseudocubically twinned. That is certainly, Each and every dice-like crystal of boleite Δαχτυλιδια skroutz is really made up of three rectangular box-like crystals oriented at ideal angles to each other. Boleite also has ΑσημÎνια Δαχτυλίδια an exceedingly eye-catching indigo color and many extremely exceptional transparent crystals are ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια Slash 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 has a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for example hematite and cassiterite, Δαχτυλιδια bulgari have the next density. Boleite's refractive index is additionally pretty large at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and while in the Mendip Hills of Somerset, England.
