Boleite was to start with found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through various revisions due to the fact its 1st discovery.
The very first specimens of boleite had been found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral from your exact same locale, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are lots of characteristics of boleite that make it of individual curiosity to collectors. For one thing, it's got an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal structure, since boleite is often pseudocubically twinned. That's, each dice-like crystal of boleite is Δαχτυλιδια swarovski actually made up of three rectangular box-like crystals oriented at suitable angles to each other. Boleite also has an exceptionally desirable indigo coloration and several very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness rating of only 3 to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a higher density. Boleite's refractive index can be quite higher at two.03-two.05; bigger than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals linked to boleite, including pseudoboleite, Δαχτυλιδια bulgari chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit in Baja, Δαχτυλιδια swarovski Mexico, boleite has been found in Damaged Hill in New South Wales, Δαχτυλιδια Γυναικεια Australia; during the Mammoth District of Arizona in the United States; and while ΛευκόχÏυσα in the Mendip Hills of Somerset, England.
