July Podicles

Welcome to our four-part series on pearls. In GT Podicle #16 (Part One), David and Jane start by looking at the pivotal role Mikimoto played in the cultivation of pearls, the biological formation of pearls, the difference between saltwater and freshwater varieties, the culturing process, and the grading methods focusing on Akoya saltwater pearls. In GT Podicle #17 (Part Two), they switch gears and look at freshwater pearls, and the role of China in the world market. In GT Podicle #18 (Part Three), our journey takes us to the Pacific Ocean and the magic of black pearls and to wrap things up, in Podicle #19 (Part Four), we end this gemmological pearl odyssey with a fascinating look at the beauty of South Sea pearls.
