This is a strand of large two-tone white/purple sea glass beads. If anything, the purple in the beads is actually slightly more pronounced than in the pictures -- but only slightly. These glass beads are made in Africa from recycled glass, and are commonly referred to as "sea glass" because they resemble beach glass. Of course, these beads aren't actually beach glass -- the matte finish is a man-made effect. These beads are created by the skilled powdered glass bead makers of the Krobo tribe, who predominantly live in Nigeria. Strands measure 20-22" long. Beads measure an average of 12 mm wide by 13-14 mm in diameter.
