Boleite was initial identified in Boleo, Mexico in 1891, within a region of the Baja peninsula that happens to be famous for exceptional minerals. Boleite is these an abnormal and complex mineral which the definition of its chemical composition and crystal framework have gone through a number of revisions because its first discovery.
The main specimens of boleite ended up identified by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral with the identical place, with an analogous framework and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are plenty of options of boleite that make it of specific fascination to collectors. For one thing, it's got an abnormal chemical composition, remaining 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's a Δαχτυλιδια Φθηνα captivating crystal framework, 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 exceptionally desirable indigo coloration and several very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly delicate, which has a Mohs hardness score of only three Δαχτυλίδια Γυναικεία to 3.five. It's got a vitreous to pearly luster. It really 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 can ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια also be incredibly higher at two.03-two.05; larger than sapphire, sphene and demantoid garnet.
In combination with cumengite, there are a number of other minerals affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in New South Δαχτυλιδια ΜοντεÏνα Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
