Add an Essential Oil to any Diffuser Jewelry Bundle and get Free Shipping. Just add your favorite essential oil to the lava beads. 3 drops off Lavender for a calming scent or Sweet Orange for a pick me up scent are 2 of my favorites. Rose Quartz, Crystal and Lava beads. Rose Quartz is known to be a stone of the heart, a crystal of Unconditional Love. It carries a soft feminine energy of peace and compassion, tenderness and healing, nourishment and comfort.
