Boleite was initially learned in Boleo, Mexico in 1891, in the area on the Baja peninsula that is now well-known for rare minerals. Boleite is these types of an unconventional and complicated mineral that the definition of its chemical composition and crystal composition have gone through numerous revisions because its first discovery.
The main specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. An additional scarce halide mineral with the identical location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct interest to collectors. For something, it has an unconventional chemical composition, currently being a hydrated lead copper silver chloride hydroxide. It has considerable quantities of those metals, with about 49% 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 Δαχτυλιδια swarovski crystals oriented at suitable angles to each other. Boleite also has an exceptionally appealing indigo coloration and several very Δαχτυλιδια ΜοντεÏνα unusual clear crystals are already cut Δαχτυλιδια ΜονοπετÏα as gemstones.

Like other halide minerals, for instance fluorite, ΑσημÎνια Δαχτυλίδια boleite is very smooth, having a Mohs hardness score of only 3 to 3.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a specific gravity of five.05. Only some minerals, including hematite and cassiterite, have the next density. Boleite's refractive index is additionally pretty large at two.03-2.05; larger than sapphire, sphene and demantoid garnet.
In combination with cumengite, there are a number 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 has been found in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in Δαχτυλιδια bulgari the United States; and while in the Mendip Hills of Somerset, England.
