Boleite was 1st found in Boleo, Mexico in 1891, inside a location with the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unusual and sophisticated mineral the definition of its chemical composition and crystal construction have been through quite a few revisions due to the fact its 1st discovery.
The initial specimens of boleite had been found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the same site, with an identical 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 something, it's got an abnormal chemical composition, being a hydrated guide copper silver chloride hydroxide. It includes sizeable quantities of these metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got an Δαχτυλιδια swarovski interesting crystal composition, considering that boleite is usually pseudocubically twinned. That is, Just about every cube-like crystal of boleite is definitely composed of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely interesting indigo colour and some quite rare clear crystals have been Slice as gemstones.

Like other halide minerals, like fluorite, boleite is kind of gentle, ΧειÏοποίητα Δαχτυλίδια which has a Mohs hardness score of only three to 3.five. It's got a vitreous to pearly luster. It really is 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 superior at 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, ΧÏυσά There are a selection of other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Along with the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South ΧÏυσά Wales, Australia; while in the Mammoth District of Arizona in America; and within the Mendip Hills of Somerset, ΧειÏοποίητα Δαχτυλίδια England.
