Porous and lightweight lava stone beads **The stone bead is made of lava stone; Lava beads are meant to be porous and light, so the lava rock beads' surface are not glossy, with some tiny hole which can soak up the oil and fragrance. They will retain the smell for a long time. After absorb the essential oil, the lava beads still can be cleaned. PERFECT DIFFUSER JEWELRY **This reusable lava stone provides the best way to diffuse essential oils on the go. Not only does it give the necklace a great look, making the antique silver stand out, but it is a porous material that will hold the oil for hours. It holds the oil longer than the traditional leather discs or poms. **How to use it? Our diffuser necklaces are easy to use! Open up the locket and place one of your lava stone inside. Drop 1-3 drops of your favorite essential oil onto the lava stone. Close locket and enjoy! It releases the oil slowly so a drop or two lasts a long time. **After you notice your essential oil smell fading you have 3 options: 1.Add a few more drops of the same oil onto the lava stone . 2.Add another oil to the lava stone to make your own personal blend. 3. Or you can gently hand wash the lava stone with water and soap. And lay out to dry.
