Boleite was initially found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through quite a few revisions considering the fact that its initially discovery.
The primary specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. A further exceptional halide mineral through the exact same location, with the same structure and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are lots of functions of boleite which make it of unique curiosity to collectors. For another thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of such metals, with about 49% guide, 14% copper and 9% silver. Next, it has an interesting crystal structure, considering the fact that boleite is usually pseudocubically twinned. That is, Just about every cube-like crystal of boleite is definitely composed of 3 rectangular box-like ΧÏυσά Δαχτυλίδια crystals oriented at correct angles to one another. Boleite also has an extremely interesting indigo colour and some quite rare clear crystals have been Slice as gemstones.

Like Δαχτυλιδια bulgari other halide minerals, like fluorite, boleite is kind of gentle, that has Δαχτυλιδια bulgari a Mohs hardness rating of only three Δαχτυλιδια Φθηνα to three.5. It's a vitreous to pearly luster. It's an unusually dense ΑσημÎνια Δαχτυλίδια mineral, with a certain gravity of five.05. Just a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in America; and within the Mendip Hills of Somerset, England.
