Boleite was 1st found in Boleo, Mexico in 1891, in a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the very same area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that make it of particular fascination to collectors. For one thing, it's got an abnormal chemical composition, being a hydrated direct copper silver chloride hydroxide. It includes sizeable quantities of such metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has an interesting crystal structure, considering the fact that boleite is usually pseudocubically twinned. That is, Just about every cube-like crystal of boleite is definitely composed of 3 rectangular box-like crystals oriented at correct angles Δαχτυλιδια swarovski to one another. Boleite also has a really interesting indigo colour plus some really scarce transparent crystals have been Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is kind of soft, Δαχτυλιδια ΜονοπετÏα by using a Mohs hardness rating ΑσημÎνια Δαχτυλίδια 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 is likewise 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, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and Δαχτυλιδια ΜοντεÏνα diaboleite.
In combination with the deposit in Baja, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
