Fluorite - Wikipedia
Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF 2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as fluorite. [6]
Fluorite (Fluorspar) : Properties, Occurrence, Uses and Deposits
2023年9月9日 · Octahedral Fluorite: Fluorite typically crystallizes in octahedral shapes, which are eight-sided. Specimens with well-defined octahedral crystals are highly valued by collectors. Cubic Fluorite: While most fluorite crystals are octahedral, cubic fluorite is characterized by cube-shaped crystals. These cubes often have sharp edges and can range ...

Fluorite Octahedron Properties and Meaning. Fluorite Octahedron is a member of the Halides family. It comes in cleaved crystalline form, in a wide variety of colors. This mineral is readily available. Read more about Fluorite Octahedron healing properties information and view the photo galleries below.
Fluorite | Common Minerals
Fluorite exhibits perfect cleavage in four directions to form octahedrons. It is most often found as a pore-filling void or vein deposit, so the fluorite crystals tend to occur as a distinct layer or series of layers lining the walls of what was originally a void in the rock.
Fluorite and Fluorspar: Mineral uses and properties - Geology.com
Fluorite can be massive, granular, or euhedral as octahedral or cubic crystals. Fluorite is a common mineral in hydrothermal and carbonate rocks worldwide. Fluorite unit cell: Illustration showing the relative size and position of fluorine and calcium ions in …

2021年12月24日 · Fluorite has perfect octahedral cleavage in multiple directions. Cleavage planes often show up in crystals as thin fracture or crack lines. Image 13 illustrates these cleavage lines in a cluster of very large (about 5 cm across) multicolor octahedrons of fluorite from the De’an Mine, Wushan, China.
Fluorite: Mineral information, data and localities. - mindat.org
Fluorite has seven main crystal forms: the most common Are the cube {100}, octahedron {111} and dodecahedron {110}; these forms having fixed Miller indices); and the tetrahexahedron {hk0}, trapezohedron {h11}, trisoctahedron {hhl} and hexoctahedron {hkl} (less common to quite rare crystal forms, having variable Miller indices).

Fluorite, as mention above, has octahedral cleavage. This means that it has four identical directions of cleavage and when cleaved in the right ways can produce a perfect octahedral shape.
