Boleite was 1st uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well-known for rare minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have undergone quite a few revisions considering the fact that its initially discovery.
The primary 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 distinctive chemical composition, was named cumengite in honor of Cumenge.
There are plenty of capabilities of boleite that make it of particular fascination to collectors. For one thing, it's got an abnormal chemical composition, being 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 has a captivating crystal construction, since boleite is usually pseudocubically twinned. Which is, Each individual cube-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at proper angles to one another. Boleite also ΑσημÎνια Δαχτυλίδια has an incredibly appealing indigo coloration and a few pretty unusual clear crystals are already cut as gemstones.

Like other halide minerals, ΛευκόχÏυσα for example fluorite, boleite is quite comfortable, with a Mohs hardness score of only 3 to 3.five. It has a vitreous to pearly luster. It ΑσημÎνια Δαχτυλίδια truly is an unusually dense mineral, with a specific gravity of five.05. Only some minerals, including hematite and ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια cassiterite, have the next density. Boleite's refractive index can also be incredibly higher at two.03-two.05; larger than sapphire, sphene and demantoid garnet.
In combination with cumengite, There are a variety of other minerals connected to boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, Δαχτυλιδια ΜοντεÏνα atacamite, mendipite and diaboleite.
Besides the deposit in Baja, Mexico, boleite continues to be present in Damaged Hill in New South Wales, Australia; in the Mammoth District of Arizona in The us; and during the Mendip Hills of Somerset, England.
