Originating in Peru, pink opal is always a popular hit year round. The soft pink hue ranges from milky white to streaks of brown and black. With its comfortable image, pink opal is always fashionable. In India, opal is thought to be the Goddess of rainbows turned to stone when fleeing from the romantic advances of the other Gods.
