Questions About 18 Mm Pearl
  • 1stDibs ExpertNovember 1, 2023
    Whether 6.5 mm pearls are too small is a matter of personal preference. Generally, 6.5-millimeter pearls are among the smallest. They can make for an understated pair of pearl studs that works well for daily wear or a dainty strand of pearls. If you're looking to make a bolder statement, you may want to consider larger pearls, as the size typically goes up to 12 to 13 millimeters. On 1stDibs, explore a large selection of pearl jewelry.
