Boleite was first found out in Boleo, Mexico in 1891, inside of a area in the Baja peninsula that is now well-known for rare minerals. Boleite is such an unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through various revisions due to the fact its very first discovery.
The initial specimens of boleite were 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 functions of boleite which make it of unique desire to collectors. For another thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has Δαχτυλιδια Γυναικεια 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 appropriate angles to each Δαχτυλιδια Μοντερνα other. Boleite also has an exceptionally desirable indigo coloration and some incredibly Δαχτυλιδια Μονοπετρα uncommon clear crystals have already been Slash as gemstones.

Like other halide minerals, for example fluorite, Χρυσά boleite is quite comfortable, with a Mohs hardness score of only three to 3.five. It has a vitreous to pearly luster. It truly is an unusually dense mineral, with a specific gravity of 5.05. Only some minerals, like hematite and cassiterite, have an increased density. Boleite's refractive index Δαχτυλιδια Μοντερνα can also be pretty higher at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals affiliated 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 usa; and in the Mendip Hills of Somerset, England.
