Garnets are a variety of gemstones also used as abrasives that are made out of silicate materials. The only characteristic that sets all species of garnets apart from each other is its chemical composition. They come in colorless, pink, black, brown, purple, green, yellow, orange, the most common of them all, red and the rarest among the species, the blue Garnet.  Garnet gemstone deposits are located in countries like Madagascar, The United States Of America, Russia, Kenya, Tanzania, and Turkey.
