Boleite was first uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well-known for rare minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal construction have undergone various revisions due to the fact its 1st discovery.
The initial 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 attributes of boleite which make it of unique curiosity to collectors. For another thing, it's an unusual chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of such metals, with Δαχτυλίδια about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal construction, because boleite Δαχτυλίδια Γυναικεία is often pseudocubically twinned. Which is, each dice-like crystal of boleite is actually made up of three rectangular box-like Δαχτυλιδια bulgari crystals oriented at suitable angles to each other. Boleite also has an exceedingly eye-catching indigo color and many extremely exceptional transparent crystals are Lower as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly soft, that has a Mohs hardness rating of only three to three.5. It's got a Δαχτυλιδια Φθηνα vitreous to pearly luster. It's an unusually dense mineral, with a selected gravity of 5.05. Just a few minerals, such as hematite and cassiterite, have a better density. Boleite's refractive index is usually really superior at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, there are a number of other minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit in Baja, Mexico, boleite Δαχτυλίδια Γυναικεία has been found in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in the United States; and while in the Mendip Hills of Somerset, England.
