Boleite was to start with uncovered in Boleo, Mexico in 1891, in the region from the Baja peninsula that has become famous for exceptional minerals. Boleite is these an abnormal and complex mineral which the definition of its chemical composition and crystal structure have gone through numerous revisions given that its initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral from the similar area, with a similar composition and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of specific desire to collectors. For something, it has an strange chemical composition, getting a hydrated lead copper silver chloride hydroxide. It has considerable quantities of those metals, with about 49% direct, 14% copper and nine% 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 in fact composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely interesting indigo shade and some quite rare clear crystals happen to be Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, with a Mohs hardness score of only three to 3.five. It's got a vitreous to pearly luster. It really is an unusually dense Δαχτυλίδια Γυναικεία mineral, with a selected gravity of 5.05. Only some minerals, like hematite and cassiterite, have an increased density. Boleite's refractive index can also be incredibly higher at two.03-two.05; larger than sapphire, Δαχτυλιδια skroutz sphene and demantoid garnet.
In combination with cumengite, There are a variety of Δαχτυλιδια skroutz other minerals affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, ΑσημÎνια Δαχτυλίδια atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite Δαχτυλίδια Γυναικεία continues to be present in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
