Boleite was first uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well known for scarce minerals. Boleite is these types of an strange and complicated mineral that the definition of its chemical composition and crystal framework have gone through a number of revisions because its to start with discovery.
The main specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another scarce 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 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 important quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That is definitely, Each and every dice-like crystal of boleite is really made up ΛευκόχÏυσα of three rectangular box-like crystals oriented at ideal angles to each other. Boleite also has a very eye-catching indigo color and many very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, for instance 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 specific gravity of five.05. Only some minerals, including hematite and cassiterite, have the next density. Boleite's refractive index Δαχτυλιδια skroutz is additionally pretty large at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
In addition to cumengite, there are a number of other minerals connected to ΛευκόχÏυσα boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Besides the deposit in Baja, Mexico, boleite has been present in Damaged Hill ΧÏυσά Δαχτυλίδια in New South Wales, Australia; during the Mammoth District of Arizona in Δαχτυλιδια swarovski The us; and from the Mendip Hills of Somerset, England.
