3 Grade AAA 8mm Lava beads hang on an 18" sterling silver cable chain. You can specify a different chain length in the options.
Lava stone is naturally porous. It is a perfect vehicle for essential oils! Simply add 1-2 drops of your favorite essential oils right onto the stone and rub it in a little (let dry before getting near clothing). The scent can last several days, depending on the oil.
