Boleite was 1st uncovered in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well known for unusual minerals. Boleite is these an strange and complicated mineral which the definition of its chemical composition and crystal framework have gone through a number of revisions given that its initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral within the similar spot, with an identical composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of specific interest to collectors. For one thing, it's got an abnormal chemical composition, staying a hydrated direct copper silver chloride hydroxide. It consists of sizeable quantities of these metals, with about 49% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal construction, since boleite is usually pseudocubically twinned. Which is, each dice-like crystal of boleite is actually made up of ΧειÏοποίητα Δαχτυλίδια a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally desirable indigo coloration and several really rare transparent Δαχτυλιδια swarovski crystals have been Reduce as gemstones.

Like other halide Δαχτυλιδια bulgari minerals, which include fluorite, boleite is fairly soft, by using a Mohs hardness ranking of only 3 to three.5. It's a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, Δαχτυλιδια ΜοντεÏνα for example hematite and cassiterite, have a higher density. Boleite's refractive index can be very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
As well as cumengite, 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 Wales, Australia; inside the Mammoth District of Arizona in America; and within the Mendip Hills ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια of Somerset, England.
