Boleite was initial found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its very first discovery.
The very first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral within the similar area, with a similar composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite that make it of specific fascination to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about 49% lead, fourteen% copper and 9% silver. Secondly, it's got an interesting crystal composition, considering that boleite is always pseudocubically twinned. That is Δαχτυλιδια swarovski 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 an exceedingly eye-catching indigo color and many extremely exceptional transparent Δαχτυλίδια Γυναικεία crystals are Reduce as gemstones.

Like other halide minerals, Δαχτυλιδια Γυναικεια for instance fluorite, boleite is very Δαχτυλιδια Φθηνα 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 is additionally incredibly higher at two.03-two.05; larger than sapphire, sphene and demantoid garnet.
In combination with cumengite, there Δαχτυλιδια Φθηνα are a number of other minerals connected to boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit in Baja, Mexico, boleite has been found in Broken Hill in New South Wales, Australia; during the Mammoth District of Arizona in the United States; and while in the Mendip Hills of Somerset, England.
