Boleite was initially discovered in Boleo, Mexico in 1891, within a area with the Baja peninsula that has grown to be famous for rare minerals. Boleite is this sort of an abnormal and complicated mineral the definition of its chemical composition and crystal framework have gone through various revisions considering the fact that its first discovery.
The very first specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. One more unusual halide mineral through the similar locale, with an analogous composition and a rather unique chemical composition, was named cumengite in honor of Cumenge.
There are plenty of features of boleite which make it of unique fascination to collectors. For something, it's an abnormal chemical composition, becoming a hydrated lead copper silver chloride hydroxide. It contains sizeable portions of those metals, with about 49% lead, fourteen% copper and nine% silver. Secondly, it has a captivating crystal composition, due to the fact boleite is usually pseudocubically twinned. That is certainly, Each and every cube-like crystal of boleite is ΛευκόχÏυσα actually made up of 3 rectangular box-like crystals oriented at correct angles to each other. Boleite also has an exceedingly interesting indigo shade and several really uncommon clear crystals are Minimize as Δαχτυλιδια ΜονοπετÏα gemstones.

Like other halide minerals, like fluorite, boleite is quite Δαχτυλιδια Γυναικεια tender, by using a Mohs hardness rating of only three to three.5. Δαχτυλιδια Γυναικεια It's got a vitreous to pearly luster. It really is an unusually dense mineral, with a specific gravity of five.05. Just a few minerals, such as hematite and cassiterite, have the next density. Boleite's refractive index can be really high at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
As well as cumengite, there are a number of other minerals connected to boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with Δαχτυλίδια Γυναικεία the deposit in Baja, Mexico, boleite has actually been found in Damaged Hill in New South Wales, Australia; inside the Mammoth District of Arizona in America; and while in the Mendip Hills of Somerset, England.
