Real fluorite glows under ultraviolet light. Fluorite hardness is very low, so there will be a lot of tiny scratches on the surface of real fluorite. Fake fluorite is mostly represented by glass or plastic. Fake fluorite made of glass can have bubbles and doesn't glow under UV light. Kilograms of fluorite can be found in every mineral shop.
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). Combinations …
Cleavage means breaking along planes defined by crystallographic directions. For example, cubic crystals like halite, NaCl, often cleave along directions that follow the cubic form. However, with a different bond strength, like fluorite $ce{CaF2}$, the crystals cleave most easily along octahedral directions, similar to two pyramids sharing a …

Fluorite exhibits perfect cleavage in four directions to form octahedrons, while quartz lacks any cleavage and breaks by conchoidal fracture. Garnet: A few varieties of garnet may be confused with rose quartz, and the two minerals have about the same hardness. Quartz, however, does not exhibit cleavage and if a garnet crystal is well formed it ...

Normally the Fluorite is only a single hue, but occasionally different colors get layered on top of each other, creating Rainbow Fluorite. Depending on the colors, experts can
Fluorite has a very low refractive index and a very low dispersion. These two characteristics enable the lens to produce extremely sharp images. Today, instead of using natural fluorite crystals to manufacture these lenses, high-purity fluorite is melted and combined with other materials to produce synthetic "fluorite" lenses of even higher ...

Fluorite forms octahedrons (figure 8). ... Fracture is breakage, which occurs in directions that are not cleavage directions. Some minerals, such as quartz, have no cleavage whatsoever. When a mineral with no cleavage is broken apart by a hammer, it fractures in all directions. Quartz is said to exhibit conchoidal fracture.
When cleaning up I found my fluorite octahedron that I got on a far away trip to Maine had been chipped at one of its points.

Information on the mineral property Cleavage. One Direction; Two Directions; Three Directions; All Directions; These identify how many "directions", or planes, the crystal is exhibiting the cleavage on. Each direction signifies the two opposite sides of a three-dimensional figure, (since opposite sides will always exhibit the same cleavage properties).
