Boleite was first learned in Boleo, Mexico in 1891, in a very area of your Baja peninsula that happens to be renowned for unusual minerals. Boleite is this sort of an unusual and sophisticated mineral the definition of its chemical composition and crystal construction have undergone quite a few revisions due to the fact its 1st discovery.
The initial specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the same site, with an identical structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are many 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 forty nine% lead, fourteen% copper and 9% silver. Secondly, it's got an interesting crystal structure, due to the fact boleite is always pseudocubically twinned. That may be, Every Δαχτυλιδια Γυναικεια 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 colour plus some really scarce transparent crystals are actually Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is kind of gentle, that has Λευκόχρυσα a Mohs hardness rating of only three to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a particular gravity Δαχτυλιδια Φθηνα of five.05. Only a few minerals, for instance hematite and cassiterite, have a higher density. Boleite's refractive index can Χρυσά be very substantial at two.03-2.05; better Δαχτυλίδια than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals associated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite is 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.
