Boleite was first uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that has become well known for scarce minerals. Boleite is these an strange and complicated mineral that the definition of its chemical composition and crystal framework have gone through a number of revisions because its to start with discovery.
The 1st 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 plenty of characteristics of boleite that make it of individual curiosity to collectors. For one thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of such metals, with about 49% lead, fourteen% copper and 9% silver. 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 color plus some really scarce transparent Δαχτυλιδια Γυναικεια crystals are actually Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly soft, 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 particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a higher density. Boleite's Δαχτυλιδια swarovski 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 Δαχτυλιδια swarovski with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and Δαχτυλιδια bulgari diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Damaged ΛευκόχÏυσα Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
