Boleite was 1st uncovered in Boleo, Mexico in 1891, in the area from the Baja peninsula that has become well known for scarce minerals. Boleite is these an strange and complicated mineral that the definition of its chemical composition and crystal framework have gone through a number of revisions because its first discovery.
The main specimens of boleite ended up found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the identical place, with an analogous framework and a slightly distinctive 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, becoming a hydrated guide copper silver chloride hydroxide. It is made up of substantial portions of these metals, with about forty nine% direct, fourteen% copper and 9% silver. Next, it's a fascinating crystal framework, given that Δαχτυλιδια bulgari boleite is often pseudocubically twinned. That is definitely, Each and every dice-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has a really beautiful indigo colour and some quite rare clear crystals happen to be Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has a Mohs hardness rating of only three to ΧειÏοποίητα Δαχτυλίδια 3.5. It's got a vitreous to pearly luster. It's an unusually dense mineral, with a selected gravity of 5.05. Just a few minerals, such as hematite and cassiterite, have a better ΑσημÎνια Δαχτυλίδια density. Boleite's refractive index is also ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια quite high at 2.03-two.05; greater than sapphire, sphene and demantoid garnet.
Besides cumengite, there are a number of other Δαχτυλίδια Γυναικεία minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit 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 inside the Mendip Hills of Somerset, England.
