Boleite was first uncovered in Boleo, Mexico in 1891, in a very area on 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 structure have been through 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 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 certain fascination to collectors. For another thing, it's 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 ΧÏυσά construction, because boleite is often pseudocubically twinned. Which is, each dice-like crystal of boleite is actually made up of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an incredibly appealing ΧειÏοποίητα Δαχτυλίδια indigo coloration and a few pretty unusual clear crystals have already been cut as gemstones.

Like Δαχτυλιδια swarovski other halide minerals, for instance fluorite, boleite is very smooth, having a Mohs hardness ranking of only 3 to 3.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a Δαχτυλίδια Γυναικεία specific gravity of five.05. Only some minerals, including hematite and cassiterite, have the next density. Boleite's refractive index is additionally pretty large at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals associated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The ΑσημÎνια Δαχτυλίδια usa; and while in the Mendip Hills of Somerset, England.
