Boleite was initial found in Boleo, Mexico in 1891, inside a location with the Baja peninsula that has grown to be recognized for exceptional minerals. Boleite is these an abnormal and complex mineral which the definition of its chemical composition and crystal framework have gone through a number of revisions because its first discovery.
The main specimens of boleite ended up identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the identical place, with an analogous framework and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are lots of attributes of boleite which make it of unique curiosity to collectors. For another thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of these metals, with about 49% guide, 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 ΑσημÎνια Δαχτυλίδια crystals oriented at right angles to one another. Boleite also has a really beautiful indigo colour plus some quite ΑσημÎνια Δαχτυλίδια rare clear crystals happen to be Slash as gemstones.

Like other halide minerals, including fluorite, boleite ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια is quite comfortable, with a Mohs hardness score of only three to 3.five. It has a vitreous to Δαχτυλιδια ΜοντεÏνα pearly luster. It truly is an unusually dense 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, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In Δαχτυλίδια Γυναικεία combination with the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and during the Mendip Hills of Somerset, England.
