Garnet is a crystalline silicate. Although the best known colour of garnets is red, they can be found in almost every colour except blue. Green garnet is similar in appearance to emerald but more brilliant and more durable. Red garnet can be confused with ruby and yellow garnet can look like topaz. There is also a non-transparent variety which looks like jade.
Garnet were believed to promote sincerity and stop anger and discord. A garnet with a lion carved on it would preserve honour and health, cure all diseases and guard the wearer from the perils of travel.
