In 1921 Kokichi Mikimoto developed a modern cultivation process for saltwater pearls and acquired important experience for the cultivation of the Akoya pearl. This new technique was of benefit for Japan and the north-west Pacific region, and in Oceania harvesting cultured pearls replaced the dangerous pearl diving. We chose from the large variety of pearls pearl jewelry that is typical for the different types of pearls and shows the almost perfect rounding of the Akoya pearls, the bright, snow-white luster of the comparatively small freshwater pearls, and the grandeur of the Tahiti cultured pearl.
