Patterns of red, brown and yellow come together in the bird's eye rhyolite 18x25mm faceted trapezoid beads from Dakota Stones. Available in 8-inch strands, these trapezoidal beads feature large cut facets for chunky style. Bands of yellow, red and brown color swirl together to create beautiful 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 fortify feelings of self respect and self value. 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.
