Boleite was very first discovered 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 various revisions considering that its very first discovery.
The very first specimens of boleite were 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 one thing, it's got an uncommon chemical composition, being a hydrated direct copper silver chloride hydroxide. It consists of significant portions of these metals, with about 49% 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 single cube-like crystal of boleite is in fact made up of a few rectangular box-like crystals oriented at appropriate angles to one another. Boleite also has an incredibly appealing indigo Δαχτυλιδια ΜοντεÏνα coloration and a few pretty unusual clear crystals are already cut as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, using a Mohs hardness ranking of only 3 to three.5. It's ΑσημÎνια Δαχτυλίδια a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and ΧÏυσά cassiterite, have a greater density. Boleite's ΧειÏοποίητα Δαχτυλίδια refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
Together with cumengite, There are Δαχτυλιδια swarovski 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 long been found in Broken Hill in New South Wales, Australia; during the Mammoth District of Arizona in the United States; and while in the Mendip Hills of Somerset, England.
