Boleite was very first found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that has grown to be popular for unusual minerals. Boleite is this sort of an uncommon and sophisticated mineral the definition of its chemical composition and crystal construction have been through various revisions due to the fact its 1st discovery.
The initial specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the exact site, with an identical structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are plenty of capabilities of boleite that make it of certain interest to collectors. For another thing, it's an unusual chemical composition, staying a hydrated direct copper silver chloride hydroxide. It consists of significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating Δαχτυλιδια bulgari crystal framework, given that boleite is often pseudocubically twinned. That is certainly, Every single cube-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally desirable indigo coloration and several very exceptional transparent crystals are Lower ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια 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 truly is an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of ΑσημÎνια Δαχτυλίδια other minerals related to boleite, which include pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite has become located in Broken Hill ΧÏυσά Δαχτυλίδια in New South Wales, Australia; inside the Mammoth District of Arizona in America; and within the Mendip Hills of Δαχτυλίδια Somerset, England.
