Boleite was 1st identified 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 construction have undergone several revisions considering the fact that its initially discovery.
The primary specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another exceptional halide mineral through the exact same location, with the same structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of specific desire to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes sizeable quantities of these metals, with about 49% lead, fourteen% copper and 9% silver. ΑσημÎνια Δαχτυλίδια Secondly, 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 fairly soft, by using a Mohs hardness rating Δαχτυλιδια Γυναικεια of only 3 to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, Δαχτυλιδια swarovski matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; Δαχτυλιδια ΜοντεÏνα within the Mammoth District of Arizona in The usa; and in the Δαχτυλιδια ΜονοπετÏα Mendip Hills of Somerset, England.
