Boleite was initially uncovered in Boleo, Mexico in 1891, within a region of the Baja peninsula that has become famous for exceptional minerals. Boleite is these an abnormal and complex mineral that the definition of its chemical composition and crystal framework have gone through a number of revisions since its first discovery.
The first specimens of boleite were being uncovered by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the similar spot, with an identical structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are many features of boleite which make it of specific desire to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% Δαχτυλίδια copper and 9% silver. Next, it has a captivating crystal construction, since boleite is often pseudocubically twinned. Which is, each dice-like crystal of boleite ΧÏυσά Δαχτυλίδια is actually made up of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally appealing indigo coloration ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια and several very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which include fluorite, boleite is very tender, Δαχτυλίδια Γυναικεία using a Mohs hardness ranking of only 3 to three.five. It has 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 Δαχτυλιδια skroutz 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.
Along with cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in America; and within the Mendip Hills of Somerset, England.
