Boleite was very first discovered in Boleo, Mexico in 1891, in a location with the Baja peninsula that is becoming recognized for rare minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through various 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 rare halide mineral within the similar area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that make it of particular fascination to collectors. For one thing, it's got an abnormal chemical composition, being a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of such 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 may be, Every single dice-like crystal of boleite is in fact made up of 3 rectangular box-like crystals oriented at right angles to Δαχτυλίδια Γυναικεία one another. Boleite also has a very beautiful indigo colour and many extremely scarce transparent crystals are actually Lower Δαχτυλιδια Γυναικεια as gemstones.

Like other halide minerals, which include fluorite, ΛευκόχÏυσα 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 example hematite and cassiterite, have a higher density. Boleite's refractive index is additionally pretty large at two.03-2.05; Δαχτυλιδια swarovski increased 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 continues to be present in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and during the Mendip Hills of Somerset, England.
