Part 2 - Diameters

When harvesting Tahiti cultured pearls, the pearl farmer performs an initial sorting, discarding all the rejects. He then makes a selection of pearls based on their diameter, shape and quality.

Pearls are classified from millimeter to millimeter and measured by the shortest diameter, which generally ranges between 8 and 14mm. This is done by sorting them through sieves. Some pearls reach 16mm and very exceptionally 18mm.

To date, the record diameter is 21mm.
