Boleite was initial learned in Boleo, Mexico in 1891, in a very area on 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 been 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 from the similar spot, with a similar composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are many options of boleite that make it of specific fascination to collectors. For something, it has an strange chemical composition, getting a hydrated guide copper silver chloride hydroxide. It has considerable portions of those metals, with about forty nine% direct, 14% copper and nine% silver. Next, it's a fascinating crystal composition, given that boleite is always pseudocubically twinned. That is definitely, Each and every cube-like crystal of boleite is in fact Δαχτυλιδια ΜοντεÏνα made up of 3 rectangular box-like crystals oriented at ideal angles to each other. Boleite also has a very eye-catching indigo color and many incredibly Δαχτυλιδια swarovski unusual clear crystals have already been cut as gemstones.

Like other halide minerals, for example fluorite, boleite is quite comfortable, with a Δαχτυλιδια bulgari Mohs hardness score of only three to 3.five. It's got a vitreous to ΛευκόχÏυσα pearly luster. It really is an unusually dense mineral, with a selected gravity of 5.05. Just a few minerals, such as hematite and cassiterite, have a better density. Boleite's refractive index is also quite high at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, Δαχτυλιδια bulgari chlorargyrite, bideauxite, 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 the Mammoth District of Arizona in America; and during the Mendip Hills of Somerset, England.
