Boleite was initial found out in Boleo, Mexico in 1891, inside of a area on the Baja peninsula that is becoming 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 considering that its initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the similar area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that make it of particular fascination to collectors. For one thing, it's got an abnormal chemical composition, being a hydrated guide copper silver chloride hydroxide. It includes sizeable quantities of these metals, with about 49% lead, fourteen% copper and 9% silver. Next, it has an interesting crystal structure, considering the fact that boleite is usually pseudocubically twinned. That's, Each individual cube-like crystal of boleite is definitely composed of a few rectangular box-like crystals oriented at proper angles to one another. Boleite also has an incredibly attractive indigo shade and a few pretty Δαχτυλιδια ΜονοπετÏα unusual clear crystals have already been cut as gemstones.

Like other halide minerals, for example fluorite, boleite is quite smooth, having a Mohs hardness score of only three to 3.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a 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 Δαχτυλιδια Γυναικεια 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 Δαχτυλιδια Γυναικεια the deposit in Baja, Mexico, boleite Δαχτυλιδια skroutz continues to be present in Damaged Hill in New South Wales, Australia; ΧÏυσά Δαχτυλίδια within the Mammoth District of Arizona in The usa; and during the Mendip Hills of Somerset, England.
