Boleite was first discovered in Boleo, Mexico in 1891, in a location of the Baja peninsula that has become well-known for rare minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through various revisions due to the fact its 1st discovery.
The initial specimens of boleite had been found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the same site, with the same structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are numerous features of boleite which make it of certain desire 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's got an interesting crystal composition, Δαχτυλιδια Γυναικεια due to the fact boleite is always pseudocubically twinned. That is, Just about every cube-like crystal of boleite Δαχτυλιδια ΜονοπετÏα is definitely composed of 3 rectangular box-like crystals oriented at correct angles to ΧÏυσά one another. Boleite also has an extremely attractive indigo shade and a few incredibly unusual clear crystals have already been cut as gemstones.

Like other halide minerals, for instance fluorite, boleite is very smooth, having a Mohs hardness score of only 3 to 3.five. It has a vitreous to pearly luster. It ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια 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 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, Δαχτυλιδια bulgari Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
