Boleite was first found in Boleo, Mexico in 1891, inside a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is this kind of an unusual and sophisticated mineral the definition of its chemical composition and crystal construction have undergone quite a few revisions considering the fact that its to start with discovery.
The 1st specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the identical location, with an analogous construction and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are plenty of characteristics of boleite that make it of individual fascination to collectors. For one thing, it's got an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It consists of significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it's got a captivating crystal framework, because boleite is often pseudocubically twinned. That is certainly, Every dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια at suitable angles to each other. Boleite also has an exceedingly desirable indigo color and several very exceptional transparent crystals are Lower as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness rating of only 3 to three.5. It's a vitreous to pearly luster. It is actually an unusually dense mineral, with a certain gravity of five.05. Only ΑσημÎνια Δαχτυλίδια some minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals ΑσημÎνια Δαχτυλίδια connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια and diaboleite.
As well as the deposit in Baja, Mexico, boleite has actually been found in Broken Hill in New Δαχτυλιδια ΜοντεÏνα South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
