| Turquoise Gemstone Information Information * Loose gemstones * Jewelry links Turquoise is a birthstone for the month of December and the gemstone representing the 11th wedding anniversary. It has been associated with horses for centuries by protecting the rider, who wears the stone, from any injuries if they were to fall off. In the 17th century, turquoise was only considered effective if received as a gift. Native Americans in the Southwest saw the stone to be sacred; and Tibetans today consider turquoise a stone of good fortune, health, and a protector against the "evil eye". |
