Types of cultured pearls
Whilst this research project has a focus on black cultured pearls, it is important to highlight that there are other types of cultured pearls produced, traded and marketed around the globe. Cultured pearls come in a wide array of colours, shapes and sizes. They are formed in different bivalve species. Marine cultured pearls are cultivated in oysters whereas freshwater cultured pearls are grown in mussels.
