Pearls are measured by their width in millimetres. The Pinctada Maxima oyster, the biggest pearl producing oyster in the world, takes two to three years to produce a single Australian South Sea pearl. As a result, our pearls have a naturally thick and lustrous nacre and are renowned for their large sizes. They typically range in size from about 11mm to 16mm in diameter although pearls of 20mm and beyond are occasionally found and highly prized.
