Boleite was initial discovered in Boleo, Mexico in 1891, in a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and complicated mineral the definition of its chemical composition and crystal structure have gone through many revisions considering that its very first discovery.
The very first specimens of boleite were learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral within the similar area, with a similar composition and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite which 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, since boleite is usually pseudocubically twinned. That's, each dice-like crystal of boleite is actually made up of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally appealing Δαχτυλίδια indigo coloration and a few pretty unusual clear crystals are already cut as gemstones.

Like other halide minerals, for example fluorite, boleite is quite smooth, with a Mohs hardness score of only three to 3.five. It has a vitreous to pearly luster. It truly is an unusually dense mineral, with a specific gravity of 5.05. Only some minerals, like hematite and cassiterite, have an increased density. Boleite's refractive index can also be incredibly higher at two.03-two.05; larger ΛευκόχÏυσα than sapphire, sphene and demantoid garnet.
In combination with cumengite, There are a variety of other minerals affiliated with boleite, Δαχτυλιδια Φθηνα which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Δαχτυλιδια skroutz Mexico, boleite continues to be present in Damaged Hill in New South Wales, Australia; within the Mammoth District of ΧÏυσά Δαχτυλίδια Arizona in The usa; and during the Mendip Hills of Somerset, England.
