Boleite was initially uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now 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 many revisions considering that its initial discovery.
The very first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more rare halide mineral from the similar area, with a similar composition and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are many options of boleite which make it of specific desire to collectors. For something, it has an strange chemical composition, getting a hydrated lead copper silver chloride hydroxide. It has considerable portions of those metals, with about forty nine% direct, 14% copper and nine% silver. Secondly, it's a fascinating crystal framework, given that boleite is often 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 exceedingly eye-catching indigo color and many extremely exceptional transparent crystals are Lower 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 ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια gravity of five.05. Only a few minerals, which include hematite and cassiterite, have a higher density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a Δαχτυλίδια Γυναικεία selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As Δαχτυλιδια bulgari well as the deposit in Baja, Mexico, boleite has long been found in Broken Hill in New South Wales, Australia; from the Mammoth Δαχτυλιδια bulgari District of Arizona in the United States; and while in the Mendip Hills of Somerset, England.
