Boleite was first uncovered in Boleo, Mexico in 1891, in a very area on the Baja peninsula that has grown to be renowned for unusual minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have undergone several revisions given that its initial discovery.
The very first specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the same locale, with the same structure and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are lots of functions of boleite that make it of unique curiosity to collectors. For one 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% lead, Δαχτυλιδια Γυναικεια fourteen% copper and nine% silver. Secondly, it has a captivating crystal framework, ΑσημÎνια Δαχτυλίδια 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 ΛευκόχÏυσα an extremely attractive indigo shade and a few pretty unusual clear crystals have already been cut as gemstones.

Like other halide minerals, for instance fluorite, boleite is very smooth, by using a Mohs hardness rating of only three to three.5. It's a vitreous to pearly luster. It really 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 Δαχτυλίδια Γυναικεία 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 combination with the deposit in Baja, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona Δαχτυλιδια bulgari in The usa; and in the Mendip Hills of Somerset, England.
