Boleite was first found out in Boleo, Mexico in 1891, inside of a area on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through many revisions given 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 similar 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 guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, Δαχτυλιδια swarovski it has an interesting crystal structure, considering the fact that boleite is usually Δαχτυλιδια bulgari pseudocubically twinned. That is, Just about ΧÏυσά every cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely interesting indigo colour and some quite rare clear crystals happen to be Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, that has a Mohs hardness rating of only three to 3.5. It's got a vitreous to pearly luster. It's Δαχτυλιδια swarovski an unusually dense mineral, with a certain gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have a greater density. Boleite's refractive index is usually really superior at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related 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 Δαχτυλίδια Γυναικεία Wales, Australia; inside the Mammoth District of Arizona in America; and in the Mendip Hills of Somerset, England.
