A Diamond Is Forever Campaign. Ayer advertising agency in 1947 transformed the diamond market. Other successful campaigns include the eternity ring meant as a symbol of continuing affection and appreciation the trilogy ring meant to represent the past present and future of a relationship and the right hand ring meant to be bought and worn by women as a symbol of independence.
