Boleite was first discovered in Boleo, Mexico in 1891, inside of 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 initially discovery.
The 1st specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral through the identical place, with an analogous framework and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite that make it of specific fascination to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it's a captivating crystal framework, because boleite is often pseudocubically twinned. Which is, each dice-like crystal Δαχτυλιδια skroutz of boleite is actually made up of three rectangular box-like crystals oriented at ΧÏυσά suitable angles to each other. Boleite also has an exceptionally desirable indigo ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια coloration 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 an unusually dense mineral, with a certain gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have a better density. ΧÏυσά Δαχτυλίδια Boleite's refractive index is usually really superior at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite has long been found in Damaged Hill in New South Wales, Australia; in the Mammoth District of Arizona in The usa; and in the Mendip Hills ΛευκόχÏυσα of Somerset, England.
