Fluorite Gemstone Information

Fluorite Gemstones

Fluorite is an attractive stone with a wide range of colors ranging from pink, purple, magenta, blue, yellow, green, red, brown and white.  Fluorite is the one of the most popular stones for mineral collectors in the world, second only to quartz. Fluorite is by far one of the most beautiful and colorful minerals available on the mineral markets.

Most specimens of fluorite have a single color but a significant percentage of fluorites have multiple colors and the colors are arranged in bands or zones that correspond to the shapes of fluorite's crystals. The typical habit of fluorite is a cube and the color zones are often in cubic arrangement. The effect is similar to phantomed crystals that appear to have crystals within crystals that are of differing colors. A fluorite crystal could have a clear outer zone allowing a cube of purple fluorite to be seen inside. Sometimes the less common habits such as a colored octahedron are seen inside of a colorless cube. One crystal of fluorite could potentially have four or five different color zones or bands (bi color or multi color). There is also a rare color change fluorite that shifts from blue to purple, depending on the lighting.

Though Fluorite's low hardness and good cleavage has limited its use in jewelry, its variable colorations and large sizes have nonetheless captivated jewelry designers and carvers the world over. Fluorite is most suitable for pendants and earrings which are not subject to wear and possible knocks or abuse.

Why Buy Loose Gemstones Instead of Pre-Set Jewelry?

There are many reasons, but basically it boils down to value and choice.

When buying your Fluorite gemstone loose instead of a pre-set stone, you can be sure you are getting the best value for your money.  Loose gemstones are less expensive, a better value, and you can really see what you are paying for.  The most important part of getting the right price and finding the best value is to first see what you're getting.  A jewelry setting will hide the inclusions inside a gem, and can deepen or brighten its color.  With a loose stone you can much more easily inspect the gem and see it for what it really is.  In this way you can get a better idea of its true worth and be sure you are paying a fair price.

The second advantage of buying a loose gemstone is choice.  You are free to pick the exact color, cut, shape and variety of the stone for the setting of your dreams, be it yellow gold, white gold, platinum or silver; prong set or bezel set with diamond accents.  You can experience the joy of creating your very own, one-of-a-kind jewelry design. Choose from a variety of jewelry settings and styles to create a completely original presentation that will perfectly suit your individual gemstone and will be as unique as you are!

Fluorite is a Calcium Fluoride by chemical composition. Pure Fluorite is in fact colorless, with the various colors resulting from tiny amounts of other elements substituting the Calcium in its crystal structure.  Fluorite is a soft gemstone, with a hardness of four.  For this reason, care should be taken to protect this gem in jewelry.  Fluorite is not recommended for rings or bracelets because of its low durability. Fluorite is most suitable for pendants and earrings, which are much less likely to be susceptible to damage.

Fluorite has a refractive index of 1.43 and no birefringence. The refractive index (RI), measured using a refractometer, is an indication of the amount light rays are bent by a mineral.  Birefringence is the difference between the minimum and maximum RI. When birefringence is high, light rays reflect off different parts of the back of a stone causing an apparent doubling of the back facets when viewed through the front facet. 

Most gems have a crystalline structure. Crystals have planes of symmetry and are divided into seven symmetry systems. The number of axes, their length, and their angle to each other determine the system to which a crystal belongs.  Fluorite crystalizes in the cubic crystal system, the same system as diamond.  Fluorite commonly forms cubes and octahedrons but can develop a variety of other forms.  Fluorite can also be massive, fibrous or botryoidal.  A rarer habit variety is the twelve sided dodecahedron however it is never seen by itself and usually modifies the cubic crystals by replacing the edges of the cube with one flat face of a dodecahedron. The tetrahexahedron is a twenty four sided habit that is also seen modifying the cubic habit. But instead of one face replacing each cubic edge, two faces modify the cube's edges. Occasionally combinations of a cube, dodecahedron and tetrahexahedron are seen producing an overall cubic crystal with no less that three minor parallel faces replacing each cubic edge. A fifth form is the hexoctahedron which modifies the cube by placing six very minor faces at each corner of the cube. Twinning is also common in fluorite and symmetrical penetration twins, especially from Cumberland England are much sought after by collectors.


Fluorite comes in basically every color, although pure Fluorite is colorless. The color variations are caused by various impurities, which are usually hydrocarbons.  The color of Fluorite is extremely variable, ranging through blue, green, yellow, colorless, brown, pink, black, and purple. Intermediate pastels between the previously mentioned colors are also possible.

The many colors of fluorite are truly wonderful. The rich purple color is by far fluorite's most famous and popular color. It easily competes with the beautiful purple of amethyst. Often specimens of fluorite and amethyst with similar shades of purple are used in mineral identification classes to illustrate the folly of using color as the sole means to identify minerals.  The blue, green and yellow varieties of fluorite are also deeply colored, popular and attractive. The colorless variety is not as well received as the colored varieties, but their rarity still makes them sought after by collectors. A brown variety found in Ohio and elsewhere has a distinctive iridescence that improves an otherwise poor color for fluorite. The rarer colors of pink, reddish orange (rose) and even black are usually very attractive and in demand.

Though most specimens of Fluorite will display a single color, it is possible for a specimen to display up to four or five different color zones or patterns. It is this banded bi color or multi color Fluorite that is most often seen in the gemstone market. In addition to this, some specimens of Fluorite will have fluorescent qualities from rare elements, un-bonded Fluorine, or organic matter within the crystal. The term fluorescent is actually derived from the word Fluorite. All of these factors will leave no doubt as to why Fluorite has earned the reputation as “The Most Colorful Mineral in the World.”


Due to its softness, faceted Fluorite is less common than most other colored stones.  Fluorite can also be found in carvings, beads and cabochons.  When faceted, Fluorite can be cut into the most common shapes and many fancy shapes as well.

Fluorite is a relatively common mineral occuring typically in vein deposits. In hydrothermal veins it can be the only mineral present, although it more commonly occurs as an accessory mineral sometimes with quartz, calcite, dolomite, barite, galena, sphalerite and other lead, silver or uranium minerals. Also as an accessory mineral in some pegmatites and in pneumatolitic veins & griesens with accesories topaz, apatite, zinnwaldite, lepidolite, tourmaline and cassiterite. Also common in veins, cavities and fractures within syenites, feldspathoidal rocks and carbonate sediments.

Fluorite occurs throughout the world, but only a handful of localities have produced large quantities of high quality Fluorite. England has produced some of the finest specimens, in areas such as Durham (especially in Weardale), Cornwall, Cumberland, and Derbyshire. Pink octahedrons were found in Göschenen, Switzerland, and are in great demand. Fine crystals were also found throughout Spain, Peru, Russia, Kazakhstan, Germany; Hunan Province, China; and Tuscany, Italy.  Canada has produced some fine crystals, in Wilberforce, Haliburton Co., Ontario, and deep green crystals in Hastings Co., Ontario.  Mexico has also produced choice specimens, in Mapimi, Durango (colorless cubes), and Niaca and Musquis, Chihuahua  (violet cubes).  The U.S. also has many fine occurrences. Hardin Co., Illinois, has produced more collectible specimens than anywhere in the U.S., in places like Rosiclare, Cave In Rock, etc. There are numerous other noteworthy deposits: Marion, Crittenden Co., Kentucky; Clay Center, Ottawa Co., Ohio; Rimer, Putnam Co., Ohio; Pea Ridge Mine, Sullivan Co., Missouri; Carthage, Smith Co., Tennessee; Grant Co., New Mexico; Barstow mine and Silverton, Ouray Co., Colorado; Penfield, Monroe Co., New York; and Walworth, Wayne Co., New York.  Green octahedrons are found in Westmoreland, New Hampshire.

Fluorite is said to enhance intuition, creativity, concentration and one's sense of order.

It is also said to promote healing, and to facilitate healing work being done with other minerals, and to give protection against many types of diseases.

Fluorite helps to release negative thoughts, and to give protection against them.

The name Fluorite means 'to flow' in Latin. The term 'florescent' also has been derived from fluorite.

Ancient Egyptians used the stone to carve statues and scarabs.

The Chinese used it in carvings for hundreds of years. The Romans used in drinking vessels in order to ward off drunkenness, along with the amethyst.

According to beliefs, the stone opens pathways in the brain to the higher dimensions of light. It increases alertness and mental activity and also helps in grasping complex and abstract concepts. The stone is also a favorite to therapists and counselors. The power of fluorite brings in objectivity and concise, orderly thoughts, actions and behavior. It encourages truth, understanding and wisdom.
