Boleite was 1st uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well known for rare 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 given that its initial discovery.
The first specimens of boleite were being uncovered by Eduoard Cumenge, a French mining engineer. Yet another rare halide mineral within the similar area, with a similar composition and a slightly different 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, 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.

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 actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a higher density. Boleite's refractive index is likewise Δαχτυλιδια Γυναικεια very substantial at 2.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, Δαχτυλιδια swarovski atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; while in Δαχτυλιδια ΜοντεÏνα the Mammoth District of Arizona in America; and within the Mendip Hills Δαχτυλιδια Φθηνα of Somerset, England.
