Boleite was initially learned 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 unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its initial discovery.
The very first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral within the similar spot, with an identical composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of specific interest to collectors. For one thing, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It is made up of substantial portions of those metals, with about forty nine% direct, 14% copper and nine% silver. Secondly, it's a fascinating crystal composition, due to the fact boleite is always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely attractive indigo shade and Δαχτυλίδια some incredibly unusual clear crystals are already cut as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, using a Mohs hardness ranking of only 3 to three.five. 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 can be very substantial at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As ΛευκόχÏυσα well as cumengite, There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, Δαχτυλιδια skroutz matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has actually been found in ΧÏυσά Broken Hill in New South Wales, Australia; while in the Mammoth District of Arizona in America; and inside the Δαχτυλίδια Mendip Hills of Somerset, England.
