Boleite was 1st found in Boleo, Mexico in 1891, inside a region with 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 through the identical place, with an analogous framework and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are plenty of options of boleite which make it of specific fascination to collectors. For something, it's got an strange chemical composition, getting a hydrated lead copper silver chloride hydroxide. It has considerable quantities of those metals, with about 49% direct, 14% ΧÏυσά Δαχτυλίδια copper and nine% silver. Secondly, it's got a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That Δαχτυλίδια may be, Every single cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at right angles to one another. Boleite Δαχτυλίδια Γυναικεία also has a really interesting indigo colour plus some quite rare clear crystals happen to be Lower as gemstones.

Like other halide minerals, such as fluorite, boleite is kind of gentle, that has a Mohs hardness rating of only three Δαχτυλιδια Γυναικεια to three.5. It's a vitreous 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 a better density. Boleite's refractive index is usually really high at 2.03-two.05; greater than sapphire, sphene and demantoid garnet.
Besides cumengite, there are a number of other minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit in Baja, Mexico, boleite has long been found in Damaged Hill in New South Wales, ΧειÏοποίητα Δαχτυλίδια Australia; during the Mammoth District of Arizona in the United States; and while in the Mendip Hills of Somerset, England.
