14 x 10mm is the average size of these beautiful freshwater Biwi pearl beads. We decided to call these biwi pearl beads "Pumpkin Spice" because they have a rich mix of autumn inspired colors. They are drilled length wise, and let me tell you, they have a gorgeous luster. Each biwi pearl bead is unique in shape, no two strands are alike. Super pretty freshwater biwi pearl beads!
