Optimum Boleite Strange Gemstones




Boleite was very first discovered in Boleo, Mexico in 1891, in a location with 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 many revisions considering that its initial discovery.

The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another uncommon halide mineral within the very same area, with a similar composition and a slightly different chemical composition, was named cumengite in honor of Cumenge.

Like other halide minerals, which include fluorite, boleite is fairly tender, using a Mohs hardness ranking Λευκόχρυσα of only 3 to three.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a particular 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-two.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, Δαχτυλιδια skroutz Mexico, boleite has been present in Damaged Hill in New South Wales, Australia; during the Mammoth District of Arizona in The us; and from the Mendip Hills of Somerset, England.
