Boleite was initial found out in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is becoming well-known for rare 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 initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the similar area, with a similar composition and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite which make it of specific fascination to collectors. For something, it's got an abnormal chemical composition, being 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 structure, Δαχτυλίδια Γυναικεία due to the fact boleite is always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a really beautiful indigo color plus some really scarce transparent crystals are actually Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly soft, by using a Mohs hardness rating of Δαχτυλίδια only 3 to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, Δαχτυλίδια have a higher density. Boleite's refractive index can be very substantial at two.03-2.05; better than sapphire, sphene and Δαχτυλιδια ΜοντεÏνα demantoid garnet.
Along with cumengite, There are a variety of other minerals associated Δαχτυλιδια Φθηνα 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 Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
