Boleite was to start with learned in Boleo, Mexico in 1891, in a very 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 composition have gone through numerous revisions since 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 those metals, with about 49% guide, 14% copper Δαχτυλιδια swarovski and nine% silver. Secondly, it's a fascinating crystal composition, given that boleite is Δαχτυλιδια Φθηνα 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 eye-catching indigo Δαχτυλιδια swarovski 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 ranking of 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 instance hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals associated Δαχτυλίδια with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite is present in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona Δαχτυλίδια Γυναικεία in The usa; and during the Mendip Hills of Somerset, England.
