Boleite was first learned in Boleo, Mexico in 1891, in a very area 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 several revisions since its initial discovery.
The very first specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral from your same locale, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are lots of attributes of boleite which make it of unique interest to collectors. For another thing, it's an unusual chemical composition, staying a hydrated guide copper silver chloride hydroxide. It is made up of considerable portions of those metals, with about forty nine% direct, 14% copper and nine% silver. Secondly, it's a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That may be, Every ΧÏυσά single cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely attractive indigo shade and a ΧειÏοποίητα Δαχτυλίδια few pretty unusual clear crystals are already cut as gemstones.

Like other halide minerals, for instance Δαχτυλίδια Γυναικεία fluorite, boleite is very tender, by using a Mohs hardness rating of only three to three.5. It's got a vitreous to pearly luster. It's an unusually dense mineral, with a certain Δαχτυλιδια Γυναικεια gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have a greater density. Boleite's refractive index is usually really superior at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has actually been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and inside ΧÏυσά Δαχτυλίδια the Mendip Hills of Somerset, England.
