As might be expected, Atlantis, the mythical lost city beneath the sea, plays a role in one important Caribbean gemstone legend. Some call larimar, the blue gem from the Dominican Republic, the "Atlantis stone" thanks to a prediction by Edgar Cayce. The man known as "the sleeping prophet" foretold of a blue stone with healing attributes that would be discovered on a Caribbean island. Today, many believe larimar is that stone and that it has the capacity to support the healing process, relieve stress, and even promote speech skills when it comes in direct contact with the skin.
