Boleite was 1st found in Boleo, Mexico in 1891, inside a location with 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 structure have been through various revisions considering that its very first discovery.
The very first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral within the very same area, with a similar framework and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are plenty of capabilities of boleite that make it of individual fascination to collectors. For one thing, it's got an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got Δαχτυλιδια ΜοντεÏνα an interesting crystal composition, considering that boleite is always pseudocubically twinned. That is Δαχτυλιδια ΜονοπετÏα definitely, Each and every dice-like crystal of boleite is really made up ΧÏυσά of three rectangular box-like crystals oriented at ideal angles to each other. Boleite also has an exceedingly eye-catching indigo color and many extremely exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is very tender, using a Mohs hardness ranking of only 3 to three.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a particular gravity of five.05. Δαχτυλιδια ΜοντεÏνα Only some minerals, for example 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.
Besides the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in New South Wales, Australia; in the Mammoth District Δαχτυλιδια swarovski of Arizona in The usa; and during the Mendip Hills of Somerset, England.
