Boleite was very first discovered in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through various revisions considering that its very first discovery.
The 1st specimens of boleite ended up identified by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral with 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 Χρυσά nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal construction, since boleite is often pseudocubically twinned. That's, Each individual dice-like crystal of boleite is actually made up 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 Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly 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. Only a few minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive index can Χρυσά Δαχτυλίδια be very substantial at two.03-2.05; better than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a selection of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to Δαχτυλιδια bulgari the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; inside the Δαχτυλιδια Γυναικεια Mammoth District of Arizona in America; Δαχτυλιδια Μονοπετρα and within the Mendip Hills of Somerset, England.
