8-9mm. We are exceptionally pleased to be able to offer these splendid lustrous A+ quality freshwater pearl beads. The color of these beauties was difficult to photograph, they are really a bit more of a peachy orange color, hence the name cantaloupe. These pearl beads are all drilled with a 2.5mm hole that will easily fit a 2mm cord... Perhaps a nice leather cord or a bunch of different textured ribbons. The design possibilities are endless with these beauties. Each strand is 8 inches with approximately 25 pearls per strand. The hole diameter of these large holed freshwater pearl beads are very consistent which is important when planning your jewelry designs. We are only able to get this color once, so get them while you can!
