RedGarnet usually belongs to either Pyrope or Almandine species but many are mixes between varieties and Spessartite garnets containing some Almandine molecules can be red as well. It has good durability and is singly refractive, meaning its colour doesn't shift with the orientation. Red Garnet was known since the Egyptian times and was a very popular stone in the ancient Rome, used for jewellery, cameos and seals. In the middle ages in Europe, garnets were believed to have special powers, often used in Viking burials to help them in reaching Valhalla or placed on the shields of knights to prevent injury. In fact, before modern tests were developed, the name "garnet" only referred to the red varieties. It comes from the Latin "granatum" meaning pomegranate, because of the resemblance of red crystals to the seeds of that fruit. Today Red Garnet remains a popular stone, mined worldwide and often used as an alternative to ruby.
