Boleite was initial discovered in Boleo, Mexico in 1891, in a location of your Baja peninsula that has grown to be renowned for unusual minerals. Boleite is this sort of an uncommon and sophisticated mineral which the definition of its chemical composition and crystal construction have undergone several revisions since its to start with discovery.
The main specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral with the identical place, with an analogous framework and a slightly unique chemical composition, was named cumengite in honor of Cumenge.
There are various characteristics of boleite that make it of individual curiosity to collectors. For another thing, it's an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It contains major quantities of such metals, with about 49% guide, 14% copper and nine% Δαχτυλίδια Γυναικεία silver. Secondly, it's got a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That is definitely, Each Δαχτυλίδια and every dice-like crystal of boleite is really made up of three Δαχτυλιδια swarovski rectangular box-like crystals oriented at ideal angles to each other. Boleite also has Δαχτυλιδια ΜονοπετÏα an exceedingly eye-catching indigo color and several very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is very tender, using a Mohs hardness ranking of only 3 to three.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, including hematite and cassiterite, have the next density. Boleite's refractive index is additionally pretty large at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals affiliated with boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Besides the deposit in Baja, Mexico, Δαχτυλιδια bulgari boleite continues to be present in Damaged Hill in New South Wales, Australia; in the Mammoth District of Arizona in The us; and from the Mendip Hills of Somerset, England.
