Boleite was to start with found out 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 complicated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another rare halide mineral through the identical locale, with a similar composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of certain desire to collectors. For something, it has an unconventional chemical composition, getting a hydrated lead copper silver chloride hydroxide. It has important quantities of those metals, with about 49% guide, 14% copper and nine% Δαχτυλιδια bulgari silver. Secondly, it's got a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is definitely composed of a few rectangular box-like crystals oriented at proper angles to one another. Boleite also has an incredibly appealing indigo coloration and a few pretty unusual transparent crystals are already Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly tender, using a Mohs hardness ranking of only 3 to three.5. It's a vitreous to pearly luster. It is actually Δαχτυλιδια swarovski an unusually dense mineral, with a particular gravity of five.05. Only a Δαχτυλιδια Γυναικεια few minerals, for instance hematite and cassiterite, have a higher density. Boleite's Δαχτυλιδια skroutz refractive index can be very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety of other minerals affiliated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has been found in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in The us; and from the Mendip Hills of Somerset, England.
