Boleite was initially found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming popular for uncommon minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal construction have undergone several revisions because its first discovery.
The first specimens of boleite were being uncovered by Eduoard Cumenge, a French mining engineer. Yet another rare halide mineral from the similar spot, with an identical composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct interest to collectors. For another thing, it has an unconventional chemical composition, staying a hydrated lead copper silver chloride hydroxide. It incorporates important quantities of such metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got an interesting crystal structure, due to the fact boleite is usually pseudocubically twinned. That Δαχτυλιδια bulgari is, Just about every cube-like crystal of boleite is in fact composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely attractive indigo shade and some incredibly uncommon clear crystals happen to be Slash as gemstones.

Like other halide minerals, including fluorite, boleite is sort of comfortable, with a Mohs hardness ranking of only 3 to three.5. It's a vitreous to pearly luster. It ΧειÏοποίητα Δαχτυλίδια is an unusually dense mineral, with a certain gravity of five.05. Just a few minerals, which include hematite and cassiterite, have a greater density. Boleite's refractive index is usually really superior at ΑσημÎνια Δαχτυλίδια 2.03-2.05; bigger than sapphire, sphene and ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and Δαχτυλιδια swarovski diaboleite.
As well as the deposit in Baja, Mexico, boleite has long been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and inside the Mendip Hills of Somerset, England.
