Natural Lava Stones are porous which enables them to absorb and diffuse your favorite essential oils that are believed to have many health benefits. Simply place 1 or 2 drops on the beads (our selection of essential oils is featured on page 55). The addition of beautiful semi-precious stones is believed to bring additional benefits. Tiger's Eye is said to relieve anxiety and bring good luck. Agate is said to enhance mental function and create a sense of security. Amethyst is said to calm and help heal physical ailments. The bracelets also have pewter beads and stretch for a perfect fit. Available in Tiger's Eye, Agate, or Amethyst.
