A Brief History of Pearls: Quality Factor Five : Size


  A brief history of pearls

QUALITY FACTOR FIVE: SIZE


An important factor in determining the quality of a pearl is its size. It's difficult for pearl farmers to cultivate large, high quality pearls. Typically, a large, high quality pearl is more valuable than a small high quality pearl.

How Are Pearls Measured?

A pearl is measured in millimeters through its diameter. The smallest pearls can be smaller than 1 millimeter in size, while the largest can be bigger than 20 millimeters in size.

Does a Pearl's Size Have Anything to Do With Value?

A pearl's size has nothing to do with its quality, but it does have quite a bit to do with its value.

With all other quality factors being equal, larger pearls are more valuable than smaller pearls are.

Most Common Pearl Sizes

The most popular pearl size is between 7 and 7.5 millimeters. Pearls larger than 7 millimeters cost more than their smaller counterparts do.
