Boleite was to start with learned in Boleo, Mexico in 1891, in a very area in the Baja peninsula that is now well-known for rare minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through various revisions due to the fact its 1st discovery.
The initial specimens of boleite had been found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral from your same locale, with an identical construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are various functions of boleite that make it of unique curiosity to collectors. For another thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver.

Like other halide minerals, for instance fluorite, boleite is very smooth, having a Mohs hardness ranking of only 3 to 3.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a particular gravity of five.05. Only some minerals, including hematite and cassiterite, have the next density. Boleite's refractive index is additionally pretty large at two.03-2.05; Χειροποίητα Δαχτυλίδια larger than sapphire, sphene and demantoid garnet.
In combination with cumengite, There are a variety of other minerals affiliated with boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and Ασημένια Δαχτυλίδια diaboleite.
Besides the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in New South Wales, Australia; Χειροποίητα Δαχτυλίδια within the Mammoth District of Arizona in The usa; and during the Δαχτυλιδια swarovski Mendip Hills of Somerset, England.
