Boleite was initial found in Boleo, Mexico in 1891, inside a region of your Baja peninsula that happens to be renowned for unusual minerals. Boleite is this sort of an uncommon and sophisticated mineral which the definition of its chemical composition and crystal construction have undergone 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. Another scarce halide mineral with the identical location, with an analogous construction and a slightly unique chemical composition, was named cumengite in honor of Cumenge.
There are various characteristics of boleite that make it of individual fascination to collectors. For one thing, it's got an uncommon chemical composition, being a hydrated direct copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has an interesting crystal structure, considering the fact that boleite is usually pseudocubically twinned. That is, Just Δαχτυλιδια skroutz about every cube-like crystal of boleite is definitely composed of a few rectangular box-like crystals oriented at correct angles to one another. Boleite also has Δαχτυλιδια skroutz an incredibly appealing indigo coloration and a few pretty unusual clear crystals are ΑσημÎνια Δαχτυλίδια already Reduce as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, using Δαχτυλίδια a Mohs hardness ranking of only 3 to three.five. It has a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial at 2.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, ΧÏυσά Δαχτυλίδια matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; while in the Mammoth District of Arizona in America; and within the Mendip Hills of Somerset, England.
