Topaz is the Birthstone for November. In ancient lore, the topaz could be used to control heat. It was said to have the power to cool boiling water, as well as excessive anger.
Imperial topaz-sherry colored varieties of brownish-yellow, orange-yellow and reddish brown-are the most popular topaz stones and command high prices, as do pink colored stones. Light blue and pale yellow topaz are of less value, but are nevertheless stunning in beauty.
Brazil is the largest producer of topaz, the most notable source being the Minas Geranis region.
Topaz was once thought to strengthen the mind, increase wisdom, and prevent mental disorders. It was thought to guard against sudden death. Powdered topaz added to wine was used to prevent asthma and insomnia. A cure for weak vision called for immersing the stone in wine for three days and nights, then rubbing the liquid on the eyes.
