Boleite was to start with learned in Boleo, Mexico in 1891, in a very location on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is this kind of an unusual and sophisticated mineral the definition of its chemical composition and crystal construction have been through quite a few revisions considering the fact that its initially discovery.
The primary specimens of boleite had been discovered by Eduoard Cumenge, a French mining engineer. A further 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 lots of functions of boleite that make it of specific desire to collectors. For something, it has an unconventional chemical composition, staying a hydrated lead copper silver chloride hydroxide. It contains substantial portions of these metals, with Δαχτυλιδια Γυναικεια about forty nine% lead, fourteen% copper and 9% silver. Next, it's a fascinating crystal framework, considering that boleite is always pseudocubically twinned. That may be, Δαχτυλίδια Γυναικεία Every single cube-like crystal of boleite is in fact composed of 3 rectangular Δαχτυλιδια Γυναικεια box-like crystals oriented at correct angles to one another. Boleite also has a Δαχτυλιδια Φθηνα really interesting indigo colour and some quite rare clear crystals have been Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of comfortable, with a Mohs hardness rating of only three to 3.5. It's got a vitreous to pearly luster. It really is an unusually dense mineral, with a selected gravity of 5.05. Just a few minerals, like hematite and cassiterite, have an ΧειÏοποίητα Δαχτυλίδια increased density. Boleite's refractive index can also be incredibly higher at two.03-two.05; larger 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 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.
