Boleite was to start with found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming recognized for rare 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 have been 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 direct copper silver chloride hydroxide. It includes sizeable quantities of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has Δαχτυλιδια swarovski an interesting crystal structure, due to the fact boleite is usually pseudocubically twinned. That is, Just about every cube-like Δαχτυλιδια bulgari crystal of boleite is definitely composed ΛευκόχÏυσα of 3 rectangular box-like crystals oriented at correct angles to one another. Boleite also has an extremely interesting indigo colour and some quite rare clear crystals have been Slice as gemstones.

Like other halide minerals, like fluorite, boleite is kind of gentle, that has a Mohs hardness rating of only three to 3.5. It's got a vitreous to pearly luster. It's an unusually dense mineral, with a certain gravity of 5.05. Just a few minerals, such as hematite Δαχτυλιδια swarovski and cassiterite, have a better 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 number of other minerals connected to boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Besides the deposit in Baja, Mexico, boleite has been present in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in The us; and Δαχτυλίδια Γυναικεία from the Mendip Hills of Somerset, England.
