Traditions hold that topaz bestowed many benefits upon its wearer. It would dispel cowardice, calm the temper, cure madness and plague, and sharpen the wit. It was also thought to aid in sleep and eliminate nightmares, as well as cure rheumatism and soreness in the joints. The stone has also been credited with being effective against bleeding and heart disease. It has been said to instantly lose its color to indicate that poison is present, thus protecting its owner. The stone has also been thought to bring fidelity and friendship if constantly worn without being set aside. It was also believed to be an effective talisman against accident and fire, and to bring increased intuition and long life. To Christians, it has been known as a symbol of uprightness and virtue.
