Boleite was first found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming popular 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 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 exceptional halide mineral through the identical location, with an analogous construction and a slightly unique chemical composition, was named cumengite in honor of Cumenge.
There are various characteristics of boleite that make it of individual curiosity to collectors. For one thing, it's got an uncommon chemical composition, remaining a hydrated direct copper silver chloride hydroxide. It includes sizeable quantities of these metals, with about 49% lead, fourteen% copper and 9% silver. Next, it has an interesting crystal construction, considering the fact that boleite is usually pseudocubically twinned. That's, Each individual cube-like crystal ΧÏυσά Δαχτυλίδια of boleite is definitely composed of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally appealing indigo ΧειÏοποίητα Δαχτυλίδια coloration and several pretty unusual transparent crystals are already Reduce as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, 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. Δαχτυλιδια Φθηνα Only a few minerals, 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, like 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; while in the Mammoth District of Arizona in America; and ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια inside the Mendip Hills of Somerset, England.
