Boleite was first uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that has become well known for scarce minerals. Boleite is these an strange and complicated mineral that the definition of its chemical composition and crystal framework have gone through a number of 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 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 has considerable quantities of those metals, with about 49% direct, 14% copper and nine% silver. Secondly, ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια it's a fascinating crystal framework, because boleite is often pseudocubically twinned. Which Δαχτυλιδια swarovski is, each dice-like crystal of boleite is actually composed of a few Δαχτυλιδια Φθηνα rectangular box-like crystals oriented at appropriate angles to one another. Boleite also has an incredibly appealing indigo shade and a few incredibly uncommon clear crystals happen to be Slash 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 selected gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have a better 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 Δαχτυλίδια other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with 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 within the Mendip Hills ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια of Somerset, England.
