Black Onxy (matte) and one single black lava rock make up this powerful mala bracelet. Solidarity is full of strength, positive energy, and a steadfastness that is tangible. A few drops of essential oil on the black lava rock will not only give you your own personal aromatherapy experience but also take this bracelet to the next level. This can be made in Mens sizes as well, please just let me know when purchasing if you would like regular size (7in) or larger. Solidarity is a powerful and beautiful thing!
