Land, sea, and sky. Past, present, and future. Father, Son, and Holy Ghost. The endless Celtic trinity knot represents all of these and more. One of the interpretations we love comes from ancient Celtic lore, which says the knot represents the phases of a woman’s life: youth, motherhood, and old age.It makes these pearl and crystal jewels a touching gift to celebrate the many moments of transformation in a woman’s life—a graduation, wedding, or promotion, becoming a mother, recovering from an illness, welcoming a first grandchild, starting a hard-earned retirement... The list, like women’s achievements, is endless.
