Garnet is the name given to a group of chemically and physically similar silica minerals. The garnets are the reddish purple grains within the rock. Most garnet found near Earth's surface forms when a sedimentary rock with a high aluminum content, such as shale, is subjected to heat and pressure intense enough to produce schist or gneiss. Garnets with a high hardness are used as an abrasive, and can be made into sandpaper known as Garnet paper. Garnet Applications . Public domain photo by Woudloper. Well formed crystals and interesting aggregates very popular among mineral collectors. These deep-source garnets are very different from the garnets that form in the crust at shallow depth. In the past 150 years, it has seen many additional uses as an industrial mineral. Mica schist can be used to make vermiculite, a common component of potting soil. Used since ancient times, garnet has accumulated its share of legends and lore. Photo by the United States Geological Survey. Let's look at what makes garnet unique. In the past 150 years, it has seen many additional uses as an industrial mineral. Public domain photo by Woudloper. Garnet particles are used to polish wood and glass, especially optical glass. Waterjet cutters are used in manufacturing and mining. This is a granular specimen approximately 11.4 centimeters across. Garnet has been used as a gemstone for thousands of years. Alluvial garnet crystals: These almandine-spessartine garnets are from an alluvial deposit in Idaho. Garnet and Talc. In these processes, a tool propels a stream of abrasive granules (also known as "media") against a surface using a highly pressurized fluid (usually air or water) as a propellant. Garnet is also used as an indicator mineral during mineral exploration and geologic assessments. They can be found as individual crystals, stream-worn pebbles, granular aggregates, and massive occurrences. It's said to strengthen your willpower, boost your confidence and success. Metaphysical Uses. These types of crystals are often weathered out of a garnet-bearing mica schist and are transported by streams. Garnet is also used as an indicator mineral during mineral exploration and geologic assessments. In addition to bringing vitality, high energy, and protection, garnet also helps build self-confidence and clarify one's life purpose. Sand Blasting: In the process of surface preparation, Super Garnet is blasted on to the surface of the steel with the use of high pressure compressed air. The first industrial use of garnet was as an abrasive. The garnet mineral almandine is harder than quartz (Mohs 7.5), but its real virtue is its sharpness, giving it cutting power without scratching wood too deeply. Diffusion of factors is highly sluggish in garnet as compared to rates in lots of different minerals, and they are also rather proof against alteration. As with all crystals and gemstones, it's important to know both the similarities between crystals, as well as the differences. The composition that is stable at the pressure and temperature conditions of Earth's mantle is pyrope, which is often found in peridotites and kimberlites, a… In that composition, "X" can be Ca, Mg, Fe2+ or Mn2+, and "Y" can be Al, Fe3+, Mn3+, V3+ or Cr3+. Corundum is the workhorse abrasive of sandpaper. Garnet helps with love and relationships because its red color symbolizes a strong love or romantic connection. It has a relatively high hardness, harder than silica sand, so small grains are used as an abrasive for both sand blasting and in sand paper. Garnet. non-metallic. Some of the diamond pipes in Canada were found by following a garnet trail produced by moving ice. Although xenoliths contain diamonds, they often contain a tremendous number of garnets for every diamond, and those garnets are generally larger in size. They all have a vitreous luster, a transparent-to-translucent diaphaneity, a brittle tenacity, and a lack of cleavage. This mineral is sharp and harder than finer-grain quartz based sandpaper. They are used in waterjet cutting, "sand" blasting, sandpaper, water filtration, and a number of other uses. Many people are familiar with almandine garnet because it is sometimes seen as dark red crystals in the igneous rocks used as granite countertops. Abrasive blasting is done in order to smooth, clean, or remove oxidation products from metals, brick, stone, and other materials. You may understand Garnet as a popular gemstone, however in its natural state garnet is a mineral found in the earth’s sediments and soils. These xenoliths are the source of most diamonds found at or near Earth's surface. Because of its hardness and other properties, garnet is also an essential industrial mineral used in abrasive products, non-slip surfaces, and filtration. Garnet's high specific gravity and high hardness reduce bed expansion and particle abrasion during backflushing. Sand Blasting: In the process of surface preparation, Super Garnet is blasted on to the surface of the steel with the use of high pressure compressed air. Garnet serves as an excellent abrasive, especially for sanding wood. Clockwise from the top left: red almandine (Madagascar), green tsavorite (Tanzania), yellow mali (Mali), orange spessartite (Mozambique), pink malaya (Tanzania), green merelani mint (Tanzania), red pyrope (Cote d'Ivoire), green demantoid (Namibia), purple rhodolite (Mozambique), and orange hessonite (Sri Lanka).
