It is believed that blue sapphires will change color to warn against an enemy’s attack.A good sapphire is brilliant, radiant, and transparent. Its rays should spread out from within, and it should not reflect any color other than its own. A good sapphire is solid. Such a stone will bring the wearer wealth, fame, a good name, health, happiness, prosperity, a long life, mental peace, and good children. Wearing a blue sapphire protects against danger, travel problems, terror, thieves, accidents and problems from storms, fire, or natural disasters. It can cause financial fortunes to change for the better, help with a person’s career, and make the wearer rich. It can free one of mental anxiety. It helps make one detached, and protects against envy. It can be worn for good luck and for protection against evil spirits. Since Saturn rules the nervous system, blue sapphires help problems of the nerves—tension and neuroses—diseases caused by an afflicted Saturn. Because Saturn is the slowest moving planet, it tends to cause chronic disease.
