Add unique patterns to your designs with the Dakota Stones brioche agate 12mm square beads. Available in 8-inch strands, these beads feature natural patterns of dark brown, white and caramel colors. Each bead features a slightly puffed square shape with rounded edges. The brecciated patterns and subtle banding would look wonderful in a chunky bracelet design. This gemstone is mined in Africa and is said to be a very good protective stone, especially for children. Pair these beads with earthy green tones for a woodland look.
