Boleite was very first found out in Boleo, Mexico in 1891, in a very location on the Baja peninsula that has grown to be popular 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 from your exact site, with an identical structure and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are various characteristics of boleite that make it of individual curiosity to collectors. For one thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It includes sizeable quantities of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal construction, since boleite is usually pseudocubically twinned. Which is, each dice-like crystal of boleite is actually made up of three rectangular box-like crystals oriented at suitable angles to each other. Boleite also has an exceptionally desirable indigo ΑσημÎνια Δαχτυλίδια color and many extremely exceptional transparent crystals are actually Lower as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly soft, by using a Mohs hardness rating Δαχτυλιδια bulgari of only 3 to three.5. It's a vitreous to pearly luster. It Δαχτυλιδια Γυναικεια is an unusually dense mineral, with a certain gravity of five.05. Only a Δαχτυλιδια skroutz few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is usually really superior at 2.03-two.05; increased than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit in Baja, ΧειÏοποίητα Δαχτυλίδια Mexico, boleite has long been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and while in the Mendip Hills of Somerset, England.
