Boleite was to start with uncovered in Boleo, Mexico in 1891, in the location from the Baja peninsula that has become famous for exceptional minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have undergone several revisions since its initially discovery.
The primary specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another exceptional halide mineral through the exact same location, with the same composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct interest to collectors. For another thing, it has an abnormal chemical composition, becoming 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 construction, because boleite is often pseudocubically twinned. Which ΑσημÎνια Δαχτυλίδια is, each dice-like crystal of boleite is actually made up of three rectangular box-like crystals oriented at suitable angles to each other. Boleite also has a very attractive indigo shade and ΑσημÎνια Δαχτυλίδια a few incredibly uncommon clear crystals happen to be Slash as gemstones.

Like other halide ΧειÏοποίητα Δαχτυλίδια minerals, including fluorite, boleite is quite comfortable, with a Mohs hardness score of only three to 3.five. It has a vitreous to pearly luster. It Δαχτυλιδια ΜοντεÏνα truly is an unusually dense mineral, with a specific gravity of 5.05. Only some minerals, like hematite and cassiterite, have an increased density. Boleite's refractive index can also be incredibly higher at two.03-two.05; larger than sapphire, ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια sphene and demantoid garnet.
In combination with cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with 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 within the Mendip Hills of Somerset, England.
