Boleite was initially discovered in Boleo, Mexico in 1891, inside of a location with the Baja peninsula that has grown to be popular for uncommon minerals. Boleite is this sort of an unusual and sophisticated mineral which the definition of its chemical composition and crystal construction have undergone quite a few revisions since its to start with discovery.
The primary specimens of boleite have been found 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 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, it has a captivating crystal composition, because boleite is often pseudocubically twinned. Which is, each dice-like crystal of boleite is actually made up of three Δαχτυλιδια Γυναικεια rectangular box-like crystals oriented at suitable angles to each other. Boleite also has an exceedingly eye-catching indigo color and many extremely exceptional transparent crystals are Δαχτυλιδια swarovski actually Lower as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly gentle, that has a Mohs hardness rating of Δαχτυλιδια bulgari only three to three.5. It's a ΛευκόχÏυσα vitreous to pearly luster. It's 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 additionally 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 diaboleite.
In addition ΛευκόχÏυσα to the deposit in Baja, Mexico, boleite has become located 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.
