Boleite was initially identified in Boleo, Mexico in 1891, within a region of the Baja peninsula that happens to be renowned for unusual minerals. Boleite is this sort of an unusual and sophisticated mineral the definition of its chemical composition and crystal construction have undergone quite a few revisions due to the fact its 1st discovery.
The initial specimens of boleite had been found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the exact site, with an identical structure and a rather distinct chemical composition, was named cumengite in honor of Cumenge.
There are many options 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 sizeable quantities of these metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got an interesting crystal composition, due to the fact boleite is always pseudocubically twinned. That is, Just about every cube-like crystal of boleite is in fact made up of three rectangular box-like crystals oriented at suitable angles to each other. Boleite also has Δαχτυλιδια Φθηνα an exceedingly desirable indigo coloration and several very exceptional transparent crystals are Reduce as gemstones.

Like Δαχτυλιδια bulgari other halide minerals, which include fluorite, boleite is fairly soft, by using Δαχτυλιδια Φθηνα a Mohs hardness ranking of only 3 to three.5. It's a vitreous to ΑσημÎνια Δαχτυλίδια pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for instance hematite and cassiterite, have a higher density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; higher than sapphire, sphene and demantoid garnet.
Along with cumengite, There are a variety 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 continues to be present in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in ΧειÏοποίητα Δαχτυλίδια The usa; and during the Mendip Hills of Somerset, England.
