9-9.5mm hugh. That's why we call these biggies. Really nice size and luster. You receive a 16" strand of top drilled freshwater pearl beads here. These pearls are perfect for those dangling designs. These pearl beads can be strung and knotted alone, or combined other types of beads for looks that range from casual to formal. Because freshwater pearls are a natural material, they will display slight variations in size and color.
