Boleite was 1st learned in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is becoming recognized for rare minerals. Boleite is this kind of an unusual and sophisticated mineral the definition of its chemical composition and crystal structure have been through quite a few revisions due to the fact its initially discovery.
The primary specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another exceptional halide mineral through the exact same location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are lots of attributes of boleite which make it of distinct interest to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It incorporates important quantities of such metals, with about Δαχτυλιδια swarovski 49% guide, 14% copper and nine% silver. Secondly, it's got an interesting crystal composition, considering that boleite is always pseudocubically twinned. That may be, Each and every dice-like crystal of boleite is Δαχτυλιδια swarovski in fact made up of 3 Δαχτυλιδια Γυναικεια rectangular box-like crystals oriented at right angles to each other. Boleite also has ΛευκόχÏυσα a very beautiful indigo colour plus some really scarce transparent crystals have been Minimize as gemstones.

Like other halide minerals, such as fluorite, boleite is kind of gentle, that has a Mohs hardness rating of only three to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a certain gravity of 5.05. Just a few minerals, which include hematite and cassiterite, Δαχτυλιδια skroutz have a greater density. Boleite's refractive index is usually really superior at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals connected with boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has actually been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in America; and inside the Mendip Hills of Somerset, England.
