Boleite was initially identified in Boleo, Mexico in 1891, within a region 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 given that its initial discovery.
The first specimens of boleite were being uncovered by Eduoard Cumenge, a French mining engineer. Yet another rare 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 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. Next, it's got an interesting crystal structure, due to the fact boleite is always pseudocubically twinned. That may be, Every single ΧÏυσά Δαχτυλίδια cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals Δαχτυλίδια oriented at correct angles to one another. Boleite also has a really interesting indigo colour plus some quite rare clear crystals have been Slice as gemstones.

Like other halide minerals, like fluorite, boleite is sort of delicate, that has a Mohs hardness rating of only three to 3.5. It's got a vitreous Δαχτυλιδια Γυναικεια to pearly luster. It's an unusually dense mineral, with a certain gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have an increased density. Boleite's refractive index can also be incredibly higher at two.03-two.05; larger than sapphire, sphene and demantoid garnet.
Besides cumengite, there are a number of other minerals connected to boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Besides the deposit Δαχτυλίδια in Baja, Mexico, boleite has been found in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in The us; and ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια from the Mendip Hills of Somerset, England.
