November claims the warm orange Topaz, but December with its cooling Season is a better fit for the Blue Topaz; I say Summer heat waves can use some of the cooling nature of this stone.
Blue Topaz in nature is very rare indeed, and tends to a very pale blue. The vivid blues available in the market have all been produced by treating white Topaz. The color change is permanent and stable.

HEALING AND MAGICAL THOUGHTS ABOUT TOPAZ:
If you dream of a blue topaz, it translates into protection and good fortune in your affairs. It is no wonder that Topaz is associated with the zodiac Sagittarius as it promotes movement in your business, action and motivation, which are strong personality traits of the December/January sign. Like the Sagittarius straight arrow shooter, Topaz promotes bold truthfulness in relationships. It helps control passions and also helps in forgiveness.
If you have thyroid issues, wearing a topaz jewelry against you or having a topaz gem on you, is very helpful. It is said that it strengthens the Thyroid. On a last note, it is also known to help blood circulation.
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.
While I wouldn't promote Topaz as a medical cure which it is not, wearing one in a beautiful jewelry setting not only helps promote all the above mentioned, but will bring a wonderfully cool and bright disposition to the wearer.
