Pearl & Gem Museum

Wander an immersive museum of pearls and the world that makes them — natural and cultured pearls and the long history of pearling, the oysters and mussels that grow them and the farms where they are raised, the famous pearls and jewels that made history, and the wider craft of gemology, each in its own gallery, so you can get to know the story behind every pearl: how it forms, what makes it precious, and the part it has played in adornment across the ages.
