Boleite was 1st uncovered in Boleo, Mexico in 1891, within a region from the Baja peninsula that happens to be famous for exceptional minerals. Boleite is these an abnormal and complex mineral which 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 have been identified by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral with the identical place, with an analogous framework and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite that make it of specific fascination to collectors. For something, it's got an abnormal chemical composition, becoming 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 construction, because boleite is often pseudocubically twinned. Which is, Each individual dice-like crystal of boleite is actually made Δαχτυλιδια ΜοντεÏνα up of three rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally appealing indigo coloration and several pretty Δαχτυλιδια swarovski unusual transparent crystals are already Reduce as gemstones.

Like other halide minerals, for instance fluorite, boleite Δαχτυλιδια Γυναικεια is very tender, using a Mohs hardness ranking of only 3 to Δαχτυλιδια skroutz three.five. It has a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and Δαχτυλιδια skroutz diaboleite.
Along with the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; while in the Mammoth District of Arizona in America; and inside the Mendip Hills of Somerset, England.
