Boleite was to start with identified in Boleo, Mexico in 1891, within a region of the Baja peninsula that happens to be renowned for unusual minerals. Boleite is these kinds of an unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through various revisions considering that its very first discovery.
The very first specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the same locale, with the same structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are numerous features of boleite which make it of certain interest to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It contains important quantities of such metals, with about 49% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal construction, because boleite is often pseudocubically twinned. Which 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 an exceedingly eye-catching indigo color and many extremely scarce transparent crystals are actually Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite ΧÏυσά Δαχτυλίδια is kind of gentle, that has a Mohs hardness rating of only 3 to three.5. It's a vitreous to pearly luster. It is actually an ΧÏυσά unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index ΧειÏοποίητα Δαχτυλίδια is likewise extremely significant at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, Δαχτυλιδια swarovski together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has long been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and while Δαχτυλιδια bulgari in the Mendip Hills of Somerset, England.
