Baroque Pearl Sizing

Q: RE: Baroque White South Sea Pearls

I am wondering if the 9-10 mm size is the smallest size (side to side) or the longest dimension of these pearls? Thank you for the clarification.

A: The pearls are measured side to side, perpendicular to the drill-hole. When the pearls are matched to make strands, the width of the pearls is a bit more evident in the graduation of size. The length of each pearl is also taken into consideration but as long as that measurement is similar, it's not as critical in making the overall completed strand and maintaining a visual and weight balance when the strand is worn.
