Colors of the earth come together in these bird's eye rhyolite 6mm roundel beads from Dakota Stones. Available in 8-inch strands, these thin, slightly cylindrical beads feature bands of red, yellow and brown color swirled together in unique patterns. Rhyolite was named "streaming rock" because of its beautiful bands, bubbles and crystal-rich layers that form as lava flows onto the surface of the stone. Rhyolite can look very different, depending on how it erupts. Rhyolite has a composition similar to granite but has a smaller grain size. Mined in Mexico, rhyolite is said to represent change, variety and progress because of its varied formational traits. Dakota Stones offers high-quality gemstones that are all useable in jewelry designs because every bead is checked to ensure they are cut and drilled correctly, that the finish is right and that the beads look distinct to their stone type.
