Boleite was to start with 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 complicated 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 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 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. Next, it has an interesting crystal construction, considering the fact that boleite is usually pseudocubically twinned. That is, Just about every cube-like Δαχτυλίδια crystal of boleite is definitely composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite Δαχτυλιδια ΜοντεÏνα also has a really beautiful indigo colour plus some really scarce transparent Δαχτυλιδια Φθηνα crystals are actually Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is Δαχτυλίδια Γυναικεία fairly soft, by using a Mohs hardness rating of 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, 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 with boleite, like 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 Δαχτυλίδια the Mendip Hills of Somerset, England.
