Boleite was initial found in Boleo, Mexico in 1891, in a region of your Baja peninsula that happens to be renowned for unusual minerals. Boleite is this sort of an uncommon and complex mineral which the definition of its chemical composition and crystal construction have been through 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 scarce halide mineral through the identical place, with an analogous framework and a slightly different chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite which make it of specific fascination to collectors. For something, it's got an strange chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It is made up of substantial portions of those metals, with about forty nine% direct, fourteen% copper and 9% silver. Next, it's a fascinating ΧÏυσά Δαχτυλίδια crystal composition, considering that boleite is always pseudocubically twinned. That may be, Every single cube-like crystal of boleite is in fact composed of 3 rectangular ΑσημÎνια Δαχτυλίδια box-like crystals oriented at correct angles to one another. Boleite also has a ΧειÏοποίητα Δαχτυλίδια really interesting indigo colour and some quite rare clear crystals happen to Δαχτυλίδια Γυναικεία be Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of comfortable, which has a Mohs hardness score of only three to 3.five. It's got a vitreous to pearly luster. It really is an unusually dense mineral, with a particular gravity of five.05. Just a few minerals, which include hematite and cassiterite, have a better density. Boleite's refractive index is usually really high at 2.03-two.05; greater than sapphire, sphene and Δαχτυλιδια swarovski demantoid garnet.
Besides cumengite, there are a number of other minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit in Baja, Mexico, boleite has long been found in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in The us; and from the Mendip Hills of Somerset, England.
