Boleite was first found out in Boleo, Mexico in 1891, inside of a location on the Baja peninsula that is becoming recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through various revisions due to the fact its 1st discovery.
The initial specimens of boleite had been found out by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral within the similar spot, with an identical composition and a rather various 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 lead copper silver chloride hydroxide. It has important quantities of those metals, with about 49% guide, 14% copper and nine% silver. Secondly, it's got a fascinating crystal composition, considering that boleite is always pseudocubically twinned. That's, Each individual dice-like crystal of boleite is actually ΧειÏοποίητα Δαχτυλίδια made up of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an exceptionally desirable indigo coloration and several very exceptional transparent crystals are Lower as gemstones.

Like other halide minerals, which include fluorite, boleite is fairly soft, by using 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 certain gravity of 5.05. Just a few minerals, which ΛευκόχÏυσα include hematite and cassiterite, have a greater density. Boleite's refractive index is usually extremely significant at 2.03-two.05; larger than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals affiliated with boleite, Δαχτυλιδια skroutz which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In ΑσημÎνια Δαχτυλίδια combination with the deposit in Baja, Mexico, boleite continues to be present in Δαχτυλίδια Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
