Boleite was initial discovered in Boleo, Mexico in 1891, in a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is this kind of an unusual 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 an identical structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are many attributes of boleite which make it of distinct interest to collectors. For another thing, 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% Δαχτυλίδια Γυναικεία silver. Secondly, it's got a fascinating crystal composition, given that boleite is often Δαχτυλιδια bulgari pseudocubically twinned. That is certainly, Every dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented at suitable angles to each other. Boleite also has an exceptionally appealing indigo coloration and a Δαχτυλιδια ΜονοπετÏα few pretty rare clear crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness rating of only 3 to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
Together with ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια cumengite, There are a selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has long been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in ΧειÏοποίητα Δαχτυλίδια the United States; and within the Mendip Hills of Somerset, England.
