Naturally, we begin with Capricorn, the sign for those whose birthdays fall between December 22 and January 19. While astrology describes Capricorns as practical, serious and ambitious, legend has it that the constellation was formed when goat nymph, Amalthea, who suckled Zeus as an infant, was placed among the stars by Zeus in gratitude. Capricorn is also associated with the idea of permanence, as it is one of the constellations that remains in the sky all year long. This zodiac stud features Capricorn coordinating symbol in 925 Sterling Silver.
