Hanadama Pearl Sizes Compared

The picture below show various size pearls compared to a U.S. dime, a number 2 pencil and a ruler. Because cultured pearls are produced by an oyster, few pearls in a strand are exactly the same size. That's why pearl sizes for a necklace are expressed as a range. When you see pearl size expressed as "6 to 6.5mm", for example, that means that no pearl in the strand is less than 6mm or greater than 6.5mm. A range variation of 0.5mm is considered an excellent size match.

The most popular size for pearl necklaces is 6.5 to 7mm. Hanadama pearls do not come larger than 9 to 9.5mm or smaller than 6.5 to 7mm.
