Boleite was initially found in Boleo, Mexico in 1891, inside a location of your Baja peninsula that has grown to be popular for uncommon minerals. Boleite is this kind of an unusual 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 similar area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite that make it of specific 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 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 made up of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a very beautiful indigo color plus some really scarce transparent 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 got a vitreous to pearly luster. It is an unusually dense mineral, with a selected gravity of 5.05. Only a few minerals, which include hematite and cassiterite, have a higher Δαχτυλιδια bulgari density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other Δαχτυλιδια bulgari minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with the deposit Δαχτυλιδια skroutz in Baja, Mexico, boleite has actually Χρυσά Δαχτυλίδια been found in Broken Hill in New South Wales, Australia; while in the Mammoth District of Arizona in America; and inside the Mendip Hills of Somerset, England.
