Boleite was initial learned in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is now well-known for rare minerals. Boleite is these types of an strange and complicated mineral that the definition of its chemical composition and crystal composition have gone through numerous revisions because its to start with discovery.
The 1st specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the identical location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct interest to collectors. For something, it has an strange chemical composition, getting a hydrated lead copper silver chloride hydroxide. It has considerable portions of those metals, with about forty Δαχτυλιδια bulgari nine% direct, 14% copper and nine% silver. Next, it's a fascinating crystal framework, because boleite is often pseudocubically twinned. Which is, each dice-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an incredibly appealing indigo coloration and a few pretty uncommon clear crystals happen to be Slash Δαχτυλίδια Γυναικεία as gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has a Mohs hardness rating of only three to 3.5. It's got a vitreous to pearly luster. It's an unusually dense mineral, with a certain gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have a greater density. Boleite's refractive index is usually extremely significant at 2.03-2.05; bigger ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals related to boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια boleite has become located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in Δαχτυλίδια Γυναικεία The usa; and in the Mendip Hills of Somerset, England.
