Boleite was first discovered in Boleo, Mexico in 1891, in a location with the Baja peninsula that is now recognized for uncommon minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have undergone quite a few 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 identical place, with an analogous framework and a slightly distinctive chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite that make it of particular desire to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal construction, since boleite is often pseudocubically twinned. Which is, Each individual dice-like crystal of boleite is actually composed of a few rectangular box-like crystals oriented at appropriate angles to Δαχτυλιδια bulgari each other. Boleite also has an exceptionally appealing indigo coloration and several very unusual transparent crystals are already Δαχτυλιδια bulgari Reduce as gemstones.

Like other halide minerals, like fluorite, boleite is sort of comfortable, with a Δαχτυλιδια skroutz Mohs hardness score of only three to 3.five. It has a vitreous Δαχτυλιδια swarovski to pearly luster. It truly is an unusually dense mineral, with a specific gravity of 5.05. Only some minerals, like hematite and cassiterite, have the next density. Boleite's refractive index can also be incredibly higher at two.03-2.05; larger than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals affiliated Χρυσά Δαχτυλίδια with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite is located in Damaged Hill in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
