A ruby is a form of the mineral corundum. The Mohs hardness scale lists the following from softer to harder: Talc 1 Gypsum 2 Calcite 3 Fluorite 4 Apatite 5 Feldspar 6 Quartz 7 Topaz
Fluorite is commonly used as the measure of hardness at the range of “4” on the Mohs scale of hardness, which one could say the “hardness of fluorite” when referring to the Mohs scale of hardness. A rare feature about fluorite is that it is the only common mineral that expresses perfect cleavage, perfect octahedron, in all four directions.
This is crushed Fluorite from 3/8″ to 1 1/2″ in size. MOHS hardness scale of 4-5. is a mineral composed of Calcium Fluoride. It is a widely occurring mineral found world wide and is often found with metallic minerals such as Galena, Sphalerite, Barite, Quartz and Calcite.
Fluorite Group. Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks.
Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Fluorite is also used as a flux in the manufacture of steel and other metals to eliminate impurities.There is a great demand for Fluorite in the optics field, and to meet it synthetic crystals are grown to produce special lenses.

Sep 29, 2006· Due to fluorite's very low hardness and perfect cleavage, it is not used for mainstream gemstone jewelry, and it is generally cut only for gemstone and mineral collectors. However, despite being a softer collector's stone,fluorite is still quite suitable for protected jewelry such as pendants, brooches or earrings.
Fluorite, also called fluorspar, common halide mineral, calcium fluoride (CaF 2), which is the principal fluorine mineral. It is usually quite pure, but as much as 20 percent yttrium or cerium may replace calcium.Fluorite occurs most commonly as a glassy, many-hued vein mineral and is often associated with lead and silver ores; it also occurs in cavities, in sedimentary rocks, in pegmatites

For example, Fluorite at four is not twice as hard as Gypsum at two; nor is the difference between Calcite and Fluorite similar to the difference between Corundum and Diamond. Hardness is used in a rough way to inform mineral identification in the field. Real minerals out in the field can look remarkably alike.
Simply put; the higher the number, the harder the mineral. Below is the Mohs Hardness Scale:" #1 Talc #2 Gypsum #3 Calcite #4 Fluorite #5 Apatite #6 Orthoclase #7 Quartz #8 Topaz #9 Corundum #10 Diamond: OTHER PROPERTIES:
For manufactured products other measures of hardness are better. Diamond is always at the top of the scale, being the hardest mineral. There are ten minerals in Mohs scale, talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum, and for last and hardest, diamond. Because the Mohs scale was made long ago, it is not exactly
With a Mohs scale, anyone can test an unknown mineral for its hardness. Imagine you have an unknown mineral. You find that it can scratch fluorite or even apatite, but feldspar scratches it. You know then that the mineral’s hardness is between 5 and 6. Note that no other mineral can scratch diamond. Cleavage and Fracture
Hardness of a gemstone is its resistance to scratching and may be described relative to a standard scale of 10 minerals known as the Mohs scale. F. Mohs, an Austrian mineralogist, developed this scale in 1822. According to Mohs' scale, the hardness of--Talc is 1 Gypsum is 2 Calcite is 3 Fluorite is 4 Apatite is 5 Feldspar is 6 Quartz is 7 Topaz
During the early 1800s, a German mineralogist named Friedrich Mohs devised a scale that tested mineral hardness, which means the resistance of a mineral to being scratched.This scale, which ran from 1 to 10, was named after Mohs, and is known as the Mohs Hardness Test.
Fluorite. Fluorite is commercially named fluorspar composed of calcium fluoride (CaF 2). It is the principal source of fluorine. The same is used in production of hydrofluoric acid, which is used in a wide variety of industrial applications including glass etching. Fluorite tends to occur in well-formed isometric crystals, forming cubes and
Apr 25, 2019· Fluorite (CaF2) is considered to be one of the most colorful minerals in the world. Common colors of fluorite include purple, green, yellow, and blue. Flourite is also visible under ultraviolet light, a property that gets its name, flourescence, from the mineral. Fluorite is often mistaken for quartz but it has a lower hardness of 4.
However, fluorite’s intermediate hardness, perfect cleavage in four directions, and common fluorescence should allow it to be easily distinguished from other minerals that share a similar appearance. Quartz: At first glance, fluorite crystals may be mistaken for quartz crystals, especially the purple variety of quartz known as amethyst.

The minerals from Mohs Scale that fall into that relative hardness range are calcite (H=3), fluorite (H=4) and apatite (H=5). By using your powers of observation and your knowledge of other physical characteristics of minerals such as crystalline structure, color, streak etc. you are able to conclude that your sample is calcite !
Fluorite crystal carries in its wonderfully intricate designs the spiritual qualities of symmetry, beauty, lucid dreams, and even genius. Its name comes from the Latin word fluor, meaning “flow,” but today, it is used to describe the crystal’s fluorescence its ability to glow under ultraviolet light..

Mohs' original hardness values are highlighted in yellow. The selection of mineral species for hardness standards is based on the common availability of the mineral.
Fluorite (CaF 2), or fluorspar, is made up of the elements calcium and fluorine. The mineral is easily identified by its perfect cleavage, color, and hardness. Fluorite occurs in cubic crystals that may be twinned. Most often, fluorite occurs as irregular masses in
Feb 27, 2020· Fluorite is a unique mineral that forms in more colors than any other mineral on Earth. The most common colors are blue, red, purple, yellow, green, and white. In developing the Mohs Scale of Mineral Hardness, Friedrich Mohs chose fluorite as the example mineral for the hardness of four (4) on the scale.. Italian mineralogist Carlo Antonio Galeani Napione named the mineral in 1797.
Fluorite is a mineral with a veritable bouquet of brilliant colors. Fluorite is well known and prized for its glassy luster and rich variety of colors. The range of common colors for fluorite starting from the hallmark color purple, then blue, green, yellow, colorless, brown,
