Boleite was first discovered in Boleo, Mexico in 1891, in a location of your Baja peninsula that has grown to be renowned for unusual minerals. Boleite is this sort of an uncommon and sophisticated mineral which the definition of its chemical composition and crystal construction have undergone several revisions since its to start with discovery.
The main specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral from the similar area, with a similar composition and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are many 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 incorporates important quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it has a captivating crystal framework, because boleite is often pseudocubically twinned. Which is, Each individual cube-like crystal Δαχτυλίδια of boleite is actually composed of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite Δαχτυλιδια swarovski also has an incredibly appealing indigo coloration and a few pretty unusual clear crystals are already cut as gemstones.

Like other Δαχτυλιδια ΜονοπετÏα halide minerals, for instance fluorite, boleite is very tender, having a Mohs hardness ranking of only 3 to three.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a specific Δαχτυλιδια Φθηνα gravity of five.05. Only some minerals, including hematite and cassiterite, have the next density. Boleite's refractive index can be very significant at 2.03-2.05; bigger 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 has been present in Damaged Hill in New South Wales, Australia; in the Mammoth District of Arizona in The us; and from the Mendip Hills of Δαχτυλίδια Somerset, England.
