Explore my Genuine Lava Rock Stone Collection of Necklaces and Bracelets currently available. Every design can be customized for size, color and accent beads. Essential Oils can be applied neatly (drops directly) to each lava stone for all day diffusion and heat disbursement. These all natural stones absorb oils and can last days without needing to reapply. Consult your own essential oils professional for tips and tricks on wearing oils neatly as there are health risks to using too much.
