Boleite was very first discovered in Boleo, Mexico in 1891, in a location with the Baja peninsula that has grown to be popular for uncommon minerals. Boleite is this kind of an unusual and sophisticated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its initial discovery.
The very first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral within the similar area, with a similar composition and a slightly various chemical composition, was named cumengite in honor of Cumenge.
There are many options of boleite which make it of specific fascination to collectors. For something, it's got an abnormal chemical composition, being a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% guide, fourteen% copper and 9% silver. Next, it has a captivating crystal framework, Δαχτυλιδια skroutz given that boleite is often pseudocubically ΧÏυσά Δαχτυλίδια twinned. That is certainly, Every dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented at suitable angles to each other. Boleite also has an exceedingly eye-catching indigo color and many extremely exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness ranking of only 3 to three.five. It's a vitreous to pearly luster. It's an unusually dense mineral, Δαχτυλίδια Γυναικεία with a selected gravity of 5.05. Just a few minerals, such as hematite and cassiterite, have an increased density. Boleite's refractive index is also incredibly higher at two.03-two.05; greater than sapphire, sphene and demantoid garnet.
In combination with cumengite, there are a number of other minerals connected to boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Besides the deposit in Baja, Mexico, boleite has been present in Damaged Hill in New South Δαχτυλιδια skroutz Wales, Australia; in the Mammoth District of Arizona in The us; and from the Mendip Hills of Somerset, Δαχτυλιδια ΜονοπετÏα England.
