The matte black onyx beads and lava bead for essential oil diffusing create a combination that is fashionable and perfect to wear with any outfit. Black onyx is the stone of protection and getting rid of negative energy while helping to develop mental stamina. Wear this bracelet during times of stress to help you feel more grounded. You can infuse the black lava bead with essential oils and enjoy the benefits of essential oils for mood enhancement. The Doterra Balance oil blend is great grounding blend and Serenity oil blend is soothing and relaxing. If you need a little pick me up, any citrus based oils are great. My favorites are Wild Orange and Citruss Bliss.
