Boleite was initial uncovered in Boleo, Mexico in 1891, within a region from the Baja peninsula that has become well known for scarce minerals. Boleite is these types of an strange and complicated mineral that the definition of its chemical composition and crystal composition have gone through numerous revisions because its first discovery.
The main specimens of boleite ended up identified by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral from your very same area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several features of boleite which make it of specific 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 has a captivating crystal Δαχτυλιδια Γυναικεια construction, since boleite is often pseudocubically twinned. That's, each dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented at ideal Δαχτυλιδια swarovski angles to each other. Boleite also Δαχτυλιδια Γυναικεια has a very eye-catching indigo color and many extremely exceptional transparent crystals Δαχτυλιδια Φθηνα are Lower as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness ranking of only 3 to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There ΧειÏοποίητα Δαχτυλίδια are a selection of other minerals connected with boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has long been found in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in The us; and from the Mendip Hills of Somerset, England.
