Boleite was initial discovered in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through various revisions considering that its very first discovery.
The very first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral from the similar spot, with an identical composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite that make it of specific fascination to collectors. For one thing, it's got an abnormal chemical composition, being a hydrated direct copper silver chloride hydroxide. It includes sizeable quantities of such metals, with about 49% lead, fourteen% copper and nine% silver.

Like other halide minerals, which include fluorite, Δαχτυλιδια swarovski boleite is fairly tender, 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 example hematite and cassiterite, have a higher density. Boleite's refractive index is additionally pretty large at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
In Δαχτυλίδια addition to cumengite, There are a variety of other minerals affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In Δαχτυλίδια combination with the deposit in Baja, Δαχτυλιδια swarovski Mexico, boleite is present in Damaged Hill in New South Wales, Australia; within Δαχτυλιδια ΜονοπετÏα the Mammoth District of Arizona in The usa; and during the Mendip Hills of Somerset, England.
