The Size of a Pearl

Qualities of Pearls - Size

A round pearl is measured across its diameter in millimetres.

For non-spherical, baroque and other shapes of pearls, both the length and width of the pearl is measured.

The most popular Akoya and Freshwater pearl sizes for earrings and necklaces are between 7 and 9mm in diameter.

South Sea and Tahitian pearls are typically worn between 9 and 11mm in diameter, or larger for more statement pieces.
