AQUAMARINE. THE PISCES BIRTHSTONE COLOR SYMBOLIZES CREATIVITY, HOPE AND COURAGE. Those born in March, under the star sign symbolized by Pisces the fish, have Aquamarine as their birthstone color. Ancient legend has it that the sky was once solid and the only pieces of it that still remain are exquisite pale blue gems. Early sailors, meanwhile, believed that aquamarine talismans etched with the likeness of Neptune would protect them from drowning at sea. Pisceans find Aquamarine soothing, something solid to hold onto. Symbolic of positive self-expression, it is said to increase youthfulness, health and happiness, making it the perfect color to enhance radiant good looks.
