Freshwater pearls typically range in size from 5mm to 12mm, though occasionally some larger sizes can be found. Freshwater pearls below 7mm are considered small in size. 7mm until 9mm are generally the more popular sizes selected for necklaces, while anything above 10mm is considered to be more rare and valuable, especially in the higher qualities. Typically the larger the freshwater pearl the more difficult it is to find a round, lustrous pearl in that size. This is especially the case in pearls over 10mm in size. |
