The crystal form of fluorite is typically cubic, but it can also occur in other forms such as octahedral, dodecahedral, or combinations of these shapes. It often displays vibrant colors due to impurities in the crystal lattice.
The color of fluorite changes due to the presence of impurities in its crystal structure. Different impurities can interact with light in various ways, influencing the color of the fluorite. This phenomenon is known as "color zoning" and can result in a wide range of colors in fluorite crystals.
The mineral described is likely fluorite, which is a non-silicate mineral containing fluorine. When exposed to ultraviolet light, fluorite can exhibit fluorescence or glow due to the presence of impurities or crystal defects that interact with the light.
Fluorite belongs to the same crystal system as salt - the cubic (also known as the isometric) crystal system.
The color of fluorite changes due to impurities in its chemical composition. Trace amounts of different elements such as iron, yttrium, or europium can cause fluorite to exhibit a range of colors, from purple and blue to yellow and green. The presence of these impurities alters the way the crystal absorbs and reflects light, resulting in varied coloration.
From a mineralogical perspective, fluorite is an evaporite mineral that contains one calcium ion and two fluorine ions. Calcium may also be substituted partially accounting for different colours of the mineral but it is usually purple.
Fluorite is a mineral consisting of cubic crystals of calcium fluorite.
The smallest and most repetitive parts of crystals like fluorite and corundum are called unit cells. Unit cells are the basic building blocks that repeat in three dimensions to form the crystal lattice structure of the entire crystal.
it depends on the shape & cut you choose!

The value of fluorite varies depending on factors such as color, clarity, and size. High quality fluorite specimens can be valuable to collectors and can range in price from a few dollars to hundreds of dollars per crystal. Rare colors and unique formations can increase the value of fluorite.
Fluorspar is a derivative of the word fluorite. Fluorite is the calcified and crystallized form of fluoride that is deep green in color.
Fluorite forms cubic crystals.
Fluorite typically breaks in a conchoidal fracture pattern, which means it breaks with curved or shell-like surfaces. This is due to its crystal structure and cleavage planes. When struck, fluorite can also exhibit a brittle fracture, breaking into irregular shapes with sharp edges.
Fluorite is a mineral composed of calcium fluoride (CaF2). Its crystal structure consists of calcium cations (Ca2+) surrounded by fluoride anions (F-) in a cubic arrangement. Fluorite is known for its wide range of colors and its fluorescence under ultraviolet light.
An antifluorite is a type of crystal structure in which the cations and anions in a crystal lattice are arranged in a specific pattern. In an antifluorite structure, the anions occupy the positions that cations would normally occupy, and vice versa. This results in a reversed or "anti" arrangement compared to the more common structure of fluorite.
Fluorite typically exhibits a crystalline texture, with well-defined crystal faces and a smooth or glassy appearance. It can also display a range of textures, such as granular, fibrous, or massive, depending on the conditions of its formation.
