The pkg size is up to you! Buy a whole economical strand or only a few beads. Make your choice in the dropdown menu "Pkg size".
The natural black color of the stone is deepened further by waxing.
Lava rock is extracted in areas with volcanic activity. These lightweight beads are always somewhat uneven with many natural cracks and bubbles inside the solid lava.
Note: the image gives you a good general idea of what the beads look like, but colors and patterns of natural stones may vary from lot to lot.
