Boleite was initially learned in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is becoming well-known for rare minerals. Boleite is such an unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through various revisions due to the fact its very first discovery.
The initial specimens of boleite were found out by Eduoard Cumenge, a French mining engineer. A different unusual halide mineral in the same 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 guide copper silver chloride hydroxide. It has 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 ΧÏυσά Δαχτυλίδια also has an exceedingly desirable indigo coloration and several very exceptional transparent crystals are Reduce as gemstones.

Like other halide minerals, which ΑσημÎνια Δαχτυλίδια include fluorite, boleite is fairly tender, by using a Mohs hardness ranking of only 3 to three.5. It's ΧειÏοποίητα Δαχτυλίδια a vitreous to pearly luster. It is an unusually dense mineral, with a Δαχτυλιδια swarovski particular gravity of five.05. Only a few minerals, which include hematite and cassiterite, have a better density. Boleite's refractive index is also quite high at 2.03-two.05; greater than sapphire, sphene and demantoid garnet.
Besides cumengite, there are a number of other minerals connected to boleite, such as pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
Together with the deposit in Baja, Mexico, boleite has been present in Damaged Hill in New South Δαχτυλιδια swarovski Wales, Australia; during the Mammoth District of Arizona in The us; and while in the Mendip Hills of Somerset, England.
