Boleite was 1st identified in Boleo, Mexico in 1891, within a region of the Baja peninsula that has become famous for exceptional minerals. Boleite is these an abnormal and complex mineral which the definition of its chemical composition and crystal framework have gone through a number of revisions because its first discovery.
The main specimens of boleite ended up found by Eduoard Cumenge, a French mining engineer. Another exceptional halide mineral through the exact same location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous 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 certainly, Each and every dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented at Δαχτυλιδια Γυναικεια ideal angles to each other. Boleite also has an exceedingly eye-catching indigo color and many very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly tender, using Δαχτυλίδια Γυναικεία a Mohs hardness ranking of only 3 to three.five. It's a vitreous Δαχτυλιδια Γυναικεια to pearly luster. It is actually Δαχτυλιδια skroutz an unusually dense mineral, with a particular gravity of five.05. Only a few 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.
In combination with the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and during the Mendip Hills of Somerset, England.
