Boleite was first learned in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well known for scarce minerals. Boleite is these kinds of an uncommon and complex mineral which the definition of its chemical composition and crystal framework have undergone several 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 exact locale, with the same 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 has an strange chemical composition, getting a hydrated direct copper silver chloride hydroxide. It is made up of considerable portions of those metals, with about forty nine% direct, 14% copper and nine% silver. Secondly, it's a fascinating crystal framework, given that boleite is often pseudocubically twinned. That is certainly, Every dice-like crystal of boleite is really made up of three rectangular box-like crystals oriented at suitable angles to each other. Boleite also has an Δαχτυλίδια exceptionally appealing indigo coloration and several very unusual transparent crystals are already cut as gemstones.

Like other halide minerals, for instance fluorite, boleite is very smooth, by using Δαχτυλίδια Γυναικεία a Mohs hardness rating of only 3 to three.5. It's a vitreous to pearly luster. It is an unusually dense mineral, with a particular gravity Δαχτυλιδια Γυναικεια of five.05. Only a few minerals, for example hematite and cassiterite, have ΛευκόχÏυσα 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, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite is located in Damaged Δαχτυλιδια ΜοντεÏνα Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
