Boleite was initial found in Boleo, Mexico in 1891, inside 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 considering the fact that its initially discovery.
The primary specimens of boleite have been found by Eduoard Cumenge, a French mining engineer. A further exceptional halide mineral through the very same site, with the same structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are many options of boleite which make it of specific desire to collectors. For one thing, it's got an abnormal chemical composition, being a hydrated guide copper silver chloride hydroxide. It includes sizeable quantities of such metals, with about 49% lead, fourteen% copper ΧειÏοποίητα Δαχτυλίδια and nine% silver. Secondly, it's got an interesting crystal composition, considering that boleite is always pseudocubically twinned. That is definitely, Each and every dice-like crystal of boleite is really made up of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely attractive indigo shade and some quite rare clear crystals happen to be Slice as ΑσημÎνια Δαχτυλίδια gemstones.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has a Mohs hardness rating of only three to 3.5. It's got a vitreous to pearly luster. It's an unusually dense mineral, with a selected gravity of 5.05. Just a few minerals, such as hematite and cassiterite, have a better density. Boleite's refractive index is usually really high at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, There Δαχτυλιδια ΜονοπετÏα are a selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, Δαχτυλιδια ΜονοπετÏα mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite is located in Broken Hill in New South ΛευκόχÏυσα Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
