How to use Black Obsidian in Fengshui
Being born out of lava, black obsidian has the potent energy of the interaction of several raw elements, including fire, earth, and water. It's categorized as volcanic glass and is very hard and smooth, but it can have incredibly sharp edges.
Also called the stone of truth, black obsidian is supposed to reveal mysteries—both about the inner world of the person working with the obsidian, as well as the inner workings of the cosmos at large. The sharpness of black obsidian is also expressed as a metaphysical property. This powerful stone can help cut through illusions, lies, fearful facades, and blockages.
