• Garnet: Mineral, January birthstone, abrasive, filter media

    What is Garnet Garnet is the name used for a large group of rock-forming minerals.These minerals share a common crystal structure and a generalized chemical composition of X 3 Y 2 (SiO 4) 3.In that composition, "X" can be Ca, Mg, Fe 2+ or Mn 2+, and "Y" can be Al, Fe 3+, Mn 3+, V 3+ or Cr 3+.. These minerals are found throughout the world in metamorphic, igneous, and sedimentary rocks.

  • Which Minerals are Used in Sand Gem Rock Auctions

    The main garnet mineral used for sand is called almandine. This mineral is sharp and harder than finer-grain quartz based sand. Garnet is used for a variety of utilities including countertops, blasting, cutting and as jewelry gemstones. Garnet is great for sanding due to its virtuous roughness.

    Garnets are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition. The different species are pyrope, almandine, spessartine, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite. The garnets make up two solid solution

  • The Composition and Application of Abrasive Garnet

    Abrasive Garnet is a type of mineral that is produced from naturally occurring almandite garnet. The right way of producing abrasive garnet is by processing beach sand and grading to exact specification. While having low free silica, Abrasive Garnet is widely used in sand/grit blasting and nowadays widely used for water jet cutting.

They all have a vitreous luster, a obvious-to-translucent diaphaneity, a brittle tenacity, and a loss of cleavage. They may be found as man or woman crystals, stream-worn pebbles, granular aggregates, and massive occurrences. Their chemical composition, unique gravity, hardness, and colorings are listed underneath.
