Boleite was very first learned in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal composition have been through many revisions due to the fact its very first 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 locale, with the same structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct interest to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It incorporates major quantities of such metals, with about 49% lead, 14% copper and nine% silver. Secondly, it's got a fascinating crystal composition, due to the fact 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 appealing indigo shade and a few pretty unusual clear crystals are already cut as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, using a Mohs hardness ranking of only three to 3.five. It has a vitreous to pearly luster. It truly Δαχτυλιδια ΜοντεÏνα is an unusually dense mineral, with a specific gravity of five.05. Only some minerals, including hematite and cassiterite, have Δαχτυλιδια bulgari the next density. Boleite's refractive index is additionally pretty large at two.03-2.05; increased than sapphire, sphene and demantoid Δαχτυλιδια skroutz garnet.
Along with cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, ΛευκόχÏυσα chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; inside the Mammoth District of Arizona in America; and within the Mendip Hills of Somerset, England.
