This bead is basically square. But it has a flat diamond on each side. The face of each diamond is smooth, making this an incredible all-purpose utility bead when you want some bling but do not want to distract from your design. Earrings, bracelets, and necklaces will all benefit from this bead. The bead is 4 mm long and 6 mm wide. It has a generous 2 mm bead channel, so you can even use it on leather projects! It is also heavy, giving a nice presence to the finished piece. Price is for 25 beads.
