Boleite was to start with uncovered in Boleo, Mexico in 1891, in the region from 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 undergone several revisions considering the fact that its initially discovery.
The 1st specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another exceptional halide mineral through the exact same location, with the same structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are numerous features of boleite which make it of specific desire to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes sizeable quantities of these metals, with about 49% lead, fourteen% copper and nine% silver. Δαχτυλίδια Secondly, it's got an interesting crystal composition, considering that boleite is always pseudocubically twinned. That is definitely, Each and every dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented at ideal angles to each other. Boleite also has a very beautiful indigo color and many extremely exceptional transparent crystals are actually Lower as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness ranking of ΧÏυσά only 3 to three.5. It's a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive index is additionally pretty large at two.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals associated Δαχτυλιδια skroutz 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 Δαχτυλιδια Φθηνα Damaged Hill in New South Wales, Australia; inside the Mammoth District of Arizona in America; and within the Mendip ΧÏυσά Hills of Somerset, England.
