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.
