Does size matter when shopping for the perfect pearl?
The answer is yes!
However, not exactly in the manner, you think. Pearls of different sizes can impact the overall appearance of a dress, match numerous styles, and suit people differently. In short, there's no straightforward answer.
Here, we provide a comparison where you can learn about the sizes of the different best-selling types of pearls and the recommended sizes so that you can make a more reasonable choice.

Freshwater pearl sizes vary from little 2.0 mm seed pearls to 11.0 - 12.0 mm. Pearl diameters consistently reach 15.0 - 16.0 mm and are even larger for some new Freshwater pearl brands, such as Edison or Souffle.

The most common sizes of freshwater pearls for necklaces, bracelets, and earrings are typically 7.0-8.0 mm, and 8.0-9.0 mm.

The average Akoya pearl oyster is around seven millimeters in size; however, they may vary between two and ten millimeters after the culturing process. Pearls below 6.0mm in size are considered on the smaller side, while anything between 6.0mm and 8.0mm is a typical size selected for pearl jewelry items on White Victoria. Akoya pearls above 8.0mm are considered above average in size, and such pearls are rare and valuable.

High-quality genuine Tahitian pearls are among the most enormous in existence, ranging in size from about 8 mm to 20mm. The average Tahitian pearl is around 13 mm in diameter. The common sizes of Tahitian pearls are 9-10mm and 10-11mm. Generally, sizes 11-12mm and above are considered above average.

South Sea Pearls range in size from 8 to 20 mm, with an average of 12 mm. In the past, finding South Sea pearls under 10 mm was rare. But, many 8 mm and 9mm pearls are being harvested for specific jewelry creations. They’re called baby South Sea pearls.
