An essential oil/aromatherapy diffusing necklace or bracelet can be made of several different materials. For example, a lava bead felt, or even leather will absorb a drop of your favorite essential oil and allow you to smell the scent when worn. It is one of the best ways to carry your essential oils with you wherever you may go. Being able to instantly 'diffuse' your favorite scents can help you overcome stressful moments or give your energy levels a boost or help you relax and unwind. We have chosen pure wool for a natural alternative and after testing also found the wool bead to hold the scent from 6 to 8 hours.
