Black Pearl Farming In French Polynesia : Illustration

RIKITEA - GAMBIER ISLANDS - FRENCH POLYNESIA - JANUARY 15: Old pearl oyster farming lines inspected by a submarine robot, on January 15, 2019 in Rikitea, French Polynesia. The Gambiers are a high place of pearl farming in Polynesia. Obtaining a cultured pearl is the result of an operation on pearl oysters called grafting. This graft consists of introducing into the animal, after an incision, a mother-of-pearl nucleus and a small piece of epithelium from the mantle of an oyster sacrificed for this purpose.(Photo by Alexis Rosenfeld/Getty Images)
