Lava Stone is an absorbent stone that is often used as a diffuser for essential oils. As an element, the stone can carry the scent of your essential oils of choice for the entire day with only a few drops. Aromatherapy is a complementary health practice that uses the scent from essential oils to help with physical and mental health. If you find that you’re dealing with a lot of stress at school, anxiety about an upcoming project at work, or if a change in the weather makes your joints ache, the Lava Stone element might be a great fit for you. The stone is black and pumice-like—a product of hot lava coming into contact with the cool earth.
