AMETHYST: is the birthstone for the month of February and the gemstone for the 4th and 6th wedding anniversary. It is derived from a Greek word meaning "not to intoxicate", which led to the belief that drinking wine from an amethyst cup would prevent drunkenness. Amethyst was thought to protect soldiers, ensure victory, aid hunters, protect against diseases, control evil thoughts, and quicken ones intelligence. It is considered to be a surface cure for headaches and toothaches; and is also used to increase spirituality.
