Lightweight lava stone is formed when molten lava cools and hardens. These exciting beads have been carved from that hardened lava. Each bead will have small hollow pockets that formed when air was released in the cooling lava, making these beads incredibly light. Due to their dark coloring, these beads work beautifully when accenting bright colors and silver components. For other naturally formed beads, shop our large selection of gemstones.
