About Pearl Size in Pearl Jewelry

Size does matter. In the same way that roses of different colors signify certain emotions or that anniversaries have traditional gifts, pearl size corresponds to the wearer’s age and is specific to different occasions.

Pearls are measured in millimeters by the diameter with the most popular sizes for pearl necklaces falling between 6.5 to 8mm. The following is a breakdown of different pearl sizes along with their respective general age brackets and significance.

Although age alone is not always the determining factor of pearl size, it is advisable to generally remain within one pearl size on either side of the age bracket. For example, on a 16 year old, a 9mm pearl necklace would look too big and may give the impression that she is too young to be wearing such pearls.

5.5mm – 6mm Pearl Size

The ideal pearl size for young teens 12 to 16 years of age. This size is also appropriate for petite women, or taller women when worn as a double or triple strand. Popular gift-giving occasions for this size include Christmas, birthdays, graduations, and coming of age celebrations such as Bat Mitzvahs and sweet sixteens.

6mm – 6.5mm Pearl Size

Generally suitable for older teens 16 to 24 years of age, who are closer to their adult height. This pearl size is also ideal for petite women and young adults who are starting new careers. Popular gift-giving occasions for this pearl size more or less follow the same guidelines as 5.5-6mm.

6.5mm – 7mm Pearl Size

Popular gift-giving occasions for this size include college graduations, weddings, Mother’s Day, and just about any other important day in a young woman’s life.

7.5mm – 8mm Pearl Size

Neither too small nor too big, an impressive size generally worn by women 30 years of age and up. This is the largest pearl size in the lower bracket of more readily available sizes. The next half size up doubles in price.
