Boleite was initially uncovered in Boleo, Mexico in 1891, within a region of the Baja peninsula that happens to be famous for exceptional minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have undergone several revisions considering the fact that its initially discovery.
The primary specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another exceptional halide mineral through the identical location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are lots of functions of boleite which make it of individual interest 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 structure, due to the fact boleite is usually pseudocubically twinned. That is, Just about every cube-like crystal of boleite ΧÏυσά Δαχτυλίδια is definitely composed of a few rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely attractive indigo shade and some incredibly uncommon clear crystals happen to be Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has a Mohs hardness score of only three to 3.5. It's got a vitreous to pearly luster. It's ΧÏυσά an unusually dense mineral, with a selected gravity of 5.05. Just a few minerals, such as hematite and cassiterite, have a better density. Boleite's refractive index is usually extremely large at two.03-2.05; ΧÏυσά increased than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals associated ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Broken Hill Δαχτυλιδια swarovski in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
